Ashur solves the following system of linear euations. -3a + 7b = -16. -9a + 5 b = 16 which statement is true about the solution to this system of equations?

a=-4, b=-4. (-4, -4).

Step-by-step explanation:

-3a+7b=-16

-9a+5b=16

-3(-3a+7b)=-3(-16)

-9a+5b=16

9a-21b=48

-9a+5b=16

-16b=64

b=64/-16

b=-4

-3a+7(-4)=-16

-3a-28=-16

-3a=-16+28

-3a=12

a=12/-3

a=-4

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
