Answer: Our answer set is( -1,-2 )Step-by-step explanation:We can use the combine method here.To single out any of the two variables, we need them to cancel out. Let us choose to cancel out y. We therefore multiply by negative 1 in the first re-arranged equation.Now we add the equationsNow we insert x into any of the two original equations;==> y = -2Our answer set is( -1,-2 )
