-3b+ac=c-4\r
\n" ); document.write( "\n" ); document.write( "Since c contains the variable to solve for, move it to the left-hand side of the equation by subtracting c from both sides.
\n" ); document.write( "ac-3b-c=-4\r
\n" ); document.write( "\n" ); document.write( "Move all terms not containing c to the right-hand side of the equation.
\n" ); document.write( "ac-c-3b=-4\r
\n" ); document.write( "\n" ); document.write( "Factor out the GCF of c from each term in the polynomial.
\n" ); document.write( "c(a)+c(-1)=3b-4\r
\n" ); document.write( "\n" ); document.write( "Factor out the GCF of c from ac-c.
\n" ); document.write( "c(a-1)=3b-4\r
\n" ); document.write( "\n" ); document.write( "Divide each term in the equation by (a-1).
\n" ); document.write( "(c(a-1))/(a-1)=(3b)/(a-1)-(4)/(a-1)\r
\n" ); document.write( "\n" ); document.write( "Simplify the left-hand side of the equation by canceling the common terms.
\n" ); document.write( "c=(3b)/(a-1)-(4)/(a-1)\r
\n" ); document.write( "\n" ); document.write( "Simplify the right-hand side of the equation by simplifying each term.
\n" ); document.write( "c=(3b-4)/(a-1) \n" ); document.write( "

\n" );
