5x - 2y = -5 [Solve using substitution]
\n" ); document.write( "y - 5x = 3
\n" ); document.write( ".
\n" ); document.write( "y-5x=3 [Pick one equation and solve for one of the variables]
\n" ); document.write( "y=5x+3 [Substitute back into the other equation]
\n" ); document.write( ".
\n" ); document.write( "5x - 2(5x+3) = -5 [Simplify]
\n" ); document.write( "5x-10x-6=-5
\n" ); document.write( "-5x=-5+6 [Solve for x]
\n" ); document.write( "-5x=1
\n" ); document.write( "x=-1/5
\n" ); document.write( ".
\n" ); document.write( "y - 5x = 3 [Plug (x=-1/5)
\n" ); document.write( "y-5(-1/5)=3
\n" ); document.write( "y+1=3 [Solve for y]
\n" ); document.write( "y=-1+3
\n" ); document.write( "y=2
\n" ); document.write( ".
\n" ); document.write( "Check by plugging (x=-1/5) and (y=2) into the other equation. \n" ); document.write( "
\n" );
