Work Step by Step

Our aim is to determine that whether the given ordered pair is a solution or not. In order to find this we will plug the given values of $x$ and $y$ , respectively. Plug $x=-3$ and $y=-4$ in the given ordered pair of equations. $3x+5=y$ or, $3x-y=-5$ $3(-3)+4=-5$ Thus, $-5=-5$ $5x-2y=-7$ $5(-3)-2(-4)=-7$ Thus, $-7 =-7$ Hence, it is a solution.
