Question

8=-5-b

Answer 1

add 5 to both sides, and divide both sides by -1.

Answer 2

We want to solve for b by itself. To do that we need to add -5 to both sides (to cancel -5 out ).

8+-5=3
Then it becomes b=3

Answer 3

Simplifying
-5 + -1b = 8

Solving
-5 + -1b = 8

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '5' to each side of the equation.
-5 + 5 + -1b = 8 + 5

Combine like terms: -5 + 5 = 0
0 + -1b = 8 + 5
-1b = 8 + 5

Combine like terms: 8 + 5 = 13
-1b = 13

Divide each side by '-1'.
b = -13

Simplifying
b = -13
