y=2x+15
\n" ); document.write( "y=4x+7 SUBTRACT.
\n" ); document.write( "-----------------
\n" ); document.write( "0=-2X+8
\n" ); document.write( "2X=8
\n" ); document.write( "X=8/2
\n" ); document.write( "X=4 ANS.
\n" ); document.write( "PROOF:
\n" ); document.write( "Y=2*4+15
\n" ); document.write( "Y=8+15
\n" ); document.write( "Y=23
\n" ); document.write( "Y=4*4+7
\n" ); document.write( "Y=16+7
\n" ); document.write( "Y=23
\n" ); document.write( "
