Answer 4

Simplifying
45 = 3b + 69

Reorder the terms:
45 = 69 + 3b

Solving
45 = 69 + 3b

Solving for variable 'b'.

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

Add '-3b' to each side of the equation.
45 + -3b = 69 + 3b + -3b

Combine like terms: 3b + -3b = 0
45 + -3b = 69 + 0
45 + -3b = 69

Add '-45' to each side of the equation.
45 + -45 + -3b = 69 + -45

Combine like terms: 45 + -45 = 0
0 + -3b = 69 + -45
-3b = 69 + -45

Combine like terms: 69 + -45 = 24
-3b = 24

Divide each side by '-3'.
b = -8

Simplifying
b = -8
