You can put this solution on YOUR website!
x+2y=-12
\n" ); document.write( "3x+8y=38\r
\n" ); document.write( "\n" ); document.write( "Multiply the top equation by -3
\n" ); document.write( "-3x -6y = 36
\n" ); document.write( " 3x +8y = 38 add these together
\n" ); document.write( " 2y = 74
\n" ); document.write( " y = 37
\n" ); document.write( "Substitute in x+2y=-12
\n" ); document.write( " x+2(37)=-12
\n" ); document.write( " x+74 = -12
\n" ); document.write( "Subtract 74 from each side
\n" ); document.write( " x = -86
\n" ); document.write( "Substitute in x+2y=-12
\n" ); document.write( " -86 + 2y=-12
\n" ); document.write( "Add 86 to each side
\n" ); document.write( " 2y = 74
\n" ); document.write( " y = 37
