You can put this solution on YOUR website!
we need to get the coefficient of x to be the same.
\n" ); document.write( "multiply the first equation through by 2
\n" ); document.write( "2x-8y=-46
\n" ); document.write( "2x+3y=9
\n" ); document.write( "subtract the two equations to eliminate the x
\n" ); document.write( "2x-2x-8y-3y=-46-9
\n" ); document.write( "-11y=-55
\n" ); document.write( "y=-55/-11
\n" ); document.write( "y=5
\n" ); document.write( "sub this number back into one of the original equations to get your x value
\n" ); document.write( "2x-8*5=-46
\n" ); document.write( "2x-40=-46
\n" ); document.write( "2x=-46+40
\n" ); document.write( "2x=-6
\n" ); document.write( "x=-3
\n" ); document.write( "your solution is x=-3, y=5 \r
