-5x +4y =-2
\n" ); document.write( "-x - y =-4
\n" ); document.write( ":
\n" ); document.write( "We need to multiply one or both equations so the coefficients of one of the

\n" ); document.write( "Multiply the 2nd equation by 4
\n" ); document.write( "-5x + 4y =-2

\n" ); document.write( "-y = -4 + 2
\n" ); document.write( "-y = -2
\n" ); document.write( "multiply both sides by -1
