Question

This should be simple but it’s Monday and my brain is fried T_T
what does “b” equal?

Answer 1

b=40 because you can make b=40 because you can easily see it sorry bad explaining

Answer 2

-10 = -b/4

to get b multiply both sides by 4

-10 *4 = -40

since b already has the negative sign the 40 would be positive

so b = 40
