3Y-5X=-33 OR 3Y=5X-33 NOW REPLACE 3Y IN THE OTHER EQUATION BY (5X-33) & SOLVE FOR X:
\n" ); document.write( "4X=(5X-33)+30
\n" ); document.write( "4X=5X-33+30
\n" ); document.write( "4X-5X=-3
\n" ); document.write( "-X=-3
\n" ); document.write( "X=-3/-1
\n" ); document.write( "X=3
\n" ); document.write( "3Y=5*3-33
\n" ); document.write( "3Y=15-33
\n" ); document.write( "3Y=-18
\n" ); document.write( "Y=-18/3
\n" ); document.write( "Y=-6 ANSWER.
