1.strategy to solve equations linear
\n" ); document.write( "In each, simply isolate the unknown to one side of the equation -- doesn't matter which side. To check your answer, plug it back into the original equation.\r
\n" ); document.write( "\n" ); document.write( "v-4(-v)=-2(2v-1)
\n" ); document.write( "distribute the 4 and -2 to each term inside parentheses:
\n" ); document.write( "v+4v=-4v+2
\n" ); document.write( "combine the v's on the left:
\n" ); document.write( "5v=-4v+2
\n" ); document.write( "add 4v to both sides:
\n" ); document.write( "9v = 2
\n" ); document.write( "finally, divide both sides by 9:
\n" ); document.write( "v = 2/9\r
\n" ); document.write( "\n" ); document.write( "9-2m/7=19
\n" ); document.write( "subtract 9 from both sides:
\n" ); document.write( "-2m/7=10
\n" ); document.write( "multiply both sides by 7:
\n" ); document.write( "-2m=70
\n" ); document.write( "divide both sides by -2:
\n" ); document.write( "m = -35\r
\n" ); document.write( "\n" ); document.write( "3(x-0.87)-2x=4.98
\n" ); document.write( "distribute the 3 to terms inside parenthesis:
\n" ); document.write( "3x-2.61-2x=4.98
\n" ); document.write( "combine x's on left:
\n" ); document.write( "3x-2.61=4.98
\n" ); document.write( "add 2.61 to both sides:
\n" ); document.write( "3x=7.59
\n" ); document.write( "divide both sides by 3:
\n" ); document.write( "x = 2.53\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2. Solve each equation by eliminating the fraction
\n" ); document.write( "x/2-x/3=5
\n" ); document.write( "multiply by a common denominator (6) to get rid of denominators:
\n" ); document.write( "6[x/2-x/3] = 6[5]
\n" ); document.write( "3x-2x=30
\n" ); document.write( "x = 30\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1k/15+5=1k/6-10
\n" ); document.write( "multiply by a common denominator (30) to get rid of denominators:
\n" ); document.write( "30[1k/15+5] = 30[1k/6-10]
\n" ); document.write( "2k+150 = 5k-300
\n" ); document.write( "150 = 3k-300
\n" ); document.write( "450 = 3k
\n" ); document.write( "150 = k\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.5b+3.4=0.2b+12.4
\n" ); document.write( "subtract 0.2b from both sides:
\n" ); document.write( "0.3b+3.4 = 12.4
\n" ); document.write( "subtract 3.4 from both sides:
\n" ); document.write( "0.3b = 9
\n" ); document.write( "b = 30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-6x+3= -7-5x
\n" ); document.write( "add 6x to both sides:
\n" ); document.write( "3= -7+x
\n" ); document.write( "add 7 to both sides:
\n" ); document.write( "10 = x\r
\n" ); document.write( "\n" ); document.write( "3-3(5-x)=0
\n" ); document.write( "distribute the -3 to both terms inside parenthesis:
\n" ); document.write( "3-15+3x = 0
\n" ); document.write( "-12+3x = 0
