You can put this solution on YOUR website!
Y-5X=3 OR Y=5X+3 NOW WE SUBSTITUTE (5X+3) FOR Y IN THE OTHER EQUATION & SOLVE FOR X:
\n" ); document.write( "5X-2(5X+3)=-5
\n" ); document.write( "5X-10X-6=-5
\n" ); document.write( "-5X=6-5
\n" ); document.write( "-5X=1
\n" ); document.write( "X=1/-5
\n" ); document.write( "X=-1/5 ANSWER.
\n" ); document.write( "Y-5*-1/5=3
\n" ); document.write( "Y+5/5=3
\n" ); document.write( "Y+1=3
\n" ); document.write( "Y=3-1
\n" ); document.write( "Y=2 ANSWER.
\n" ); document.write( "PROOF
\n" ); document.write( "5*-1/5-2*2=-5
\n" ); document.write( "-5/5-4=-5
\n" ); document.write( "-1-4=-5
\n" ); document.write( "-5=-5
\n" ); document.write( "I'LL LEAVE THE REST FOR YOU TO SOLVE USING THE SAME PROCEDURE!
\n" ); document.write( " \n" ); document.write( "
