Answer

The given ordered pair is not a solution.

Work Step by Step

We have $$2x-3y = -9$$ $$4x+2y = -2$$ Possible solution $(3,5)$ Substituting on Equation (1) $$2(3)-3(5) = -9$$ $$6 - 15 = -9$$ $$-9=-9$$ Substituting on Equation (2) $$4(3) +2(5) = -2$$ $$12+10 = -2$$ $$22=-2$$ The given ordered pair is not a solution.
