1) the greater of two numbers is 12 more than the smaller and the sum of the two numbers is 10 find the numbers\r
\n" ); document.write( "\n" ); document.write( "Let's say the greater number=A, the smaller number=a.
\n" ); document.write( "Form equations:
\n" ); document.write( "A = a + 12.... (1)
\n" ); document.write( "A + a = 10.... (2)\r
\n" ); document.write( "\n" ); document.write( "Substitute (1) in (2):
\n" ); document.write( "A + a = 10
\n" ); document.write( "(a + 12) + a = 10
\n" ); document.write( "a + 12 + a = 10
\n" ); document.write( "12 + 2a = 10
\n" ); document.write( "2a = 10 - 12
\n" ); document.write( "a = -2/2
\n" ); document.write( "a = -1.... (3)\r
\n" ); document.write( "\n" ); document.write( "Substitute (3) in (1)
\n" ); document.write( "A = a + 12
\n" ); document.write( "A = -1 + 12
\n" ); document.write( "A = 11\r
\n" ); document.write( "\n" ); document.write( "Therefore, the greater number is 11 and the smaller number is -1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2) one number is 5 times another if 18 is subtracted from the greater the remainder will be 3 times the smaller find the numbers
\n" ); document.write( "Assuming: \"One number is 5 times another. If 18 is subtracted from the greater, the remainder will be 3 times the smaller. Find the numbers.\"\r
\n" ); document.write( "\n" ); document.write( "Assume: X = the greater number, x = the smaller number\r
\n" ); document.write( "\n" ); document.write( "Form equations:
\n" ); document.write( "N=5n .... (1)
\n" ); document.write( "N-18=3n.... (2)\r
\n" ); document.write( "\n" ); document.write( "Substitute (1) in (2)
\n" ); document.write( "N-18=3n
\n" ); document.write( "5n-18=3n
\n" ); document.write( "5n-3n=18
\n" ); document.write( "2n=18
\n" ); document.write( "n=18/2
\n" ); document.write( "n=9\r
\n" ); document.write( "\n" ); document.write( "Substitute n=9 in (1)
\n" ); document.write( "N=5n
\n" ); document.write( "N=5*9
\n" ); document.write( "N=45\r
\n" ); document.write( "\n" ); document.write( "Therefore, the greater number is 45 and the smaller number is 9.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3) divide 534 into three parts such that the second part will be 32 less than twice the first and the third will be 18 more than the first.\r
\n" ); document.write( "\n" ); document.write( "Assume: first part=a, second part=b, third part=c
\n" ); document.write( "Form equations:
\n" ); document.write( "a+b+c=534....(1)
\n" ); document.write( "b-32=2a
\n" ); document.write( "b=2a+32....(2)
\n" ); document.write( "c+18=a....(3)\r
\n" ); document.write( "\n" ); document.write( "Substitute (3) in (2)
\n" ); document.write( "b=2a+32
\n" ); document.write( "b=2(c+18)+32
\n" ); document.write( "b=2c+36+32
\n" ); document.write( "b=2c+68....(4)\r
\n" ); document.write( "\n" ); document.write( "Substitute (3) and (4) in (1)
\n" ); document.write( "a+b+c=534
\n" ); document.write( "(c+18)+(2c+68)+c=534
\n" ); document.write( "c+18+2c+68+c=534
\n" ); document.write( "4c+86=534
\n" ); document.write( "4c=534-86
\n" ); document.write( "c=448/4
\n" ); document.write( "c=112\r
\n" ); document.write( "\n" ); document.write( "Substitute c=112 in (4)
\n" ); document.write( "b=2c+68
\n" ); document.write( "b=2(112)+68
\n" ); document.write( "b=224+68
\n" ); document.write( "b=292\r
\n" ); document.write( "\n" ); document.write( "Substitute c=112, b=292 in (1)
\n" ); document.write( "a+b+c=534
\n" ); document.write( "a+292+112=534
\n" ); document.write( "a=534-292-112
\n" ); document.write( "a=130\r
\n" ); document.write( "\n" ); document.write( "So, the first part=130, the second part=292 and the third part=112.
