(z-7)+6=2.1(3z+1)
\n" ); document.write( "First you multiply.
\n" ); document.write( "z-7=6.2z+2.1
\n" ); document.write( "Now combine like terms.
\n" ); document.write( "z-6.2z=2.1+7
\n" ); document.write( "-5.2z=9.1
\n" ); document.write( "z=9.1/-5.2
\n" ); document.write( "z=-1.75 answer.
\n" ); document.write( "Proof:
\n" ); document.write( "-1.75-7=6.2*-1.75+2.1
\n" ); document.write( "-8.75=-10.85+2.1
\n" ); document.write( "-8.75=-8.75\r
