Ok first use the Distributive Property to get rid of the parentheses so
\n" ); document.write( "18x - (8x - 7) = 67
\n" ); document.write( "multiply -1 times 8x and -1 times -7 to get
\n" ); document.write( "18x - 8x + 7 = 67
\n" ); document.write( "Now combine like terms
\n" ); document.write( "10x + 7 = 67
\n" ); document.write( "Next subtract 7 from both sides of the equal sign
\n" ); document.write( "10x + 7 - 7 = 67 - 7
\n" ); document.write( "10x = 60
\n" ); document.write( "Finally to solve for x divide each side of the equal sign by 10
\n" ); document.write( "10x/10 = 60/10
\n" ); document.write( "x = 6
\n" ); document.write( "To check just plug 6 into the original equation
\n" ); document.write( "-----------------------------------------------------------------------------
\n" ); document.write( "The second problem also starts the Distributive Property
\n" ); document.write( "11 ( 4 - 6y) + 5 ( 13y + 11) = 9
\n" ); document.write( "First 11 is multiplied by 4 and -6y
\n" ); document.write( "44 - 66y + 5 ( 13y + 11) = 9
\n" ); document.write( "Then 5 is multiplied by 13y and 11
\n" ); document.write( "44 - 66y + 65y + 55 = 9
\n" ); document.write( "Now combine like terms
\n" ); document.write( "99 - 1y = 9
\n" ); document.write( "add 1y to both sides
\n" ); document.write( "99 -1y + 1y = 9 + 1y
\n" ); document.write( "99 = 9 + y
\n" ); document.write( "subtract 9 from both sides
\n" ); document.write( "99 - 9 = 9 - 9 + y
\n" ); document.write( "90 = y
\n" ); document.write( "
\n" );
