You can put this solution on YOUR website!
substitute x=-4 and y=-15 to find the value of this expression
\n" ); document.write( " -3(4x-y)
\n" ); document.write( "Is all you are going to do is to replace x with -4 and y with -15;
\n" ); document.write( "-3(4(-4)-(-15))
\n" ); document.write( "-3(-16-(-15))
\n" ); document.write( "-3(-16+15)
\n" ); document.write( "-3(-1)=3
\n" ); document.write( "Hope this helps!
\n" ); document.write( "=)
