Answer:
(-3, 5)
Step-by-step explanation:
plug y = 5 into the second equation
x(5) = -15
5x = -15
x = -3
(-3, 5)
First, substitute the x for 5.
7 (4+x)
7 (4+5)
Then follow P.E.M.D.A.S.
So first you have to solve what's in the parenthesis.
7 (4 + 5)
7 (9)
Then you multiply the 7 & the 9 which is 63
So the answer is 63.
