You can put this solution on YOUR website!
7(a+b)=b-a
\n" ); document.write( "4(3a+2b)=b-8
\n" ); document.write( "-----------------
\n" ); document.write( "If you want to solve for a & b, you should say that.
\n" ); document.write( "---
\n" ); document.write( "7(a+b)=b-a --> 7a + 7b = b - a ---> 8a = -6b ---> a = -3b/4
\n" ); document.write( "=====================
\n" ); document.write( "4(3a+2b)=b-8 --> 12a + 8b = b-8
\n" ); document.write( "Sub for a
\n" ); document.write( "12*(-3b/4) + 8b = b-8
\n" ); document.write( "You can do the rest\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
