Answer:
b=2
Explanation:
Simplifying
5b + 8 + -2b = 7b
Reorder the terms:
8 + 5b + -2b = 7b
Combine like terms: 5b + -2b = 3b
8 + 3b = 7b
Solving
8 + 3b = 7b
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-7b' to each side of the equation.
8 + 3b + -7b = 7b + -7b
Combine like terms: 3b + -7b = -4b
8 + -4b = 7b + -7b
Combine like terms: 7b + -7b = 0
8 + -4b = 0
Add '-8' to each side of the equation.
8 + -8 + -4b = 0 + -8
Combine like terms: 8 + -8 = 0
0 + -4b = 0 + -8
-4b = 0 + -8
Combine like terms: 0 + -8 = -8
-4b = -8
Divide each side by '-4'.
b = 2
Simplifying
b = 2
