-2(4x+5)=3(x+4) need to see exactly how you solve this problem.
\n" ); document.write( ":
\n" ); document.write( "multiply what's inside the brackets
\n" ); document.write( "-8x - 10 = 3x + 12
\n" ); document.write( ";
\n" ); document.write( "add 8x to both sides
\n" ); document.write( "-10 = 3x + 8x + 12
\n" ); document.write( ":
\n" ); document.write( "subtract 12 from both sides, add the x's
\n" ); document.write( "-10 - 12 = 11x
\n" ); document.write( "-22 = 11x
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by 11
\n" ); document.write( "x = \"%28-22%29%2F11\"
\n" ); document.write( "x = -2
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in original equation
\n" ); document.write( "-2(4x+5)=3(x+4)
\n" ); document.write( "replace x with -2
\n" ); document.write( "-2(4(-2) + 5) = 3(-2 + 4)
\n" ); document.write( "-2(-8+5) = 3(2)
\n" ); document.write( "-2(-3) = 6
\n" ); document.write( "6 = 6; confirms our solution of x=-2 \n" ); document.write( "
\n" );
