Step-by-step explanation:
Answer:
x= -8
Explain:
You first have to make the variable by itself so you subtract 3 on both sides. The x is by itself and you finish by subtracting -5 to 3 and you get the answer x = -8
Hope this helps
Area = 140
16 x 8 = 128
16-12 = 4
(6x4)/2 = 12
128 + 12= 140
Answer:

Step-by-step explanation:
Given

Now we know that system has infinite solution for x

in above equation.

∴
I would solve it for B, but that's just what I think. So you would do -12 time -2 which is 24, then subtract 24 from both sides so that you would get B=-31
