solving for x in the following problem: 3(cx-b)+c = ax+d/a
\n" ); document.write( ":
\n" ); document.write( "3(cx-b) + c = \"%28%28ax%2Bd%29%29%2Fa\"
\n" ); document.write( ":
\n" ); document.write( "Get rid of the denominator, multiply equation by a and you have:
\n" ); document.write( "3a(cx-b) + ac = ax + d
\n" ); document.write( ":
\n" ); document.write( "3acx - 3ab + ac = ax + d
\n" ); document.write( ":
\n" ); document.write( "Add 3ab to both sides, subtract ac from both sides
\n" ); document.write( "3acx = ax + 3ab + d - ac
\n" ); document.write( ":
\n" ); document.write( "subtract ax from both sides:
\n" ); document.write( "3acx - ax = 3ab - ac + d
\n" ); document.write( ":
\n" ); document.write( "Factor out x on the left and factor out a on the right
\n" ); document.write( "x(3ac - a) = a(3b - c) + d
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by (3ac-a)
\n" ); document.write( "x = \"%28%28a%283b-c%29%2Bd%29%29%2F%28%283ac-a%29%29\"
\n" ); document.write( ":
\n" ); document.write( "x = \"%28a%283b-c%29%2Bd%29%2F%28a%283c-1%29%29\"
\n" ); document.write( "
\n" );
