(-1.3,-18.8)
you would start by substituting y=6x-11 into -2x-3y=-7
so it would look like
-2x-3(6x-11)=-7
once you solve for x you would then take the x value of -1.3 and put it into the equation y=6x-11 so it would look like this
y=6(-1.3)-11
which would get you y=-18.8
to check you would put both the x and y value back into -2x-3y=-7 and boom answer
