Answer:
-16-72v
Step-by-step explanation:
-8*2 = -16
-8*9v = -72v
so, -16 + (-72v) -> -16-72v
X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60
4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20
x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5
Its A. x=4
procedure: 3*equation1 - 2*equation2 ⇒ x=4
