Algebra.Com's Answer #2774 by guapa(62)![]() ![]() ![]() You can put this solution on YOUR website! Let x be the smaller number then y is the greater. \n" ); document.write( "The sum (+) of two numbers (x, y) is (=) 23. Thus, x+y=23 This is our first equation. \n" ); document.write( "You can solve this equation for x or y. Let's do it for x. x=23-y \n" ); document.write( "Now, twice the greater number (2y) added (+) to three times the smaller number (3x)is 57 (=57) \n" ); document.write( "So, the second equation is: 2y + 3x = 57 \n" ); document.write( "Now substitute (23-y) for x: \n" ); document.write( "2y + 3(23-y)=57 \n" ); document.write( "2y+ 69-3y= 57 \n" ); document.write( "69-y=57 \n" ); document.write( "y=12 \n" ); document.write( "If y =12 then x=23-y equals x=23-12, x= 11 \n" ); document.write( "Now we can check our answers: x+y = 23, 11+12=23 \n" ); document.write( "And 2y+3x = 57, 2(12)+3(11)=57, 24+33=57 \n" ); document.write( " |
