Question

(1/2)b+4=(1/8)b+88

Answer 1

Try getting all the "b" terms on the left side of the equation and all the number terms on the right.
(1/2)b - (1/8)b = 88 - 4 (subtract (1/8)b and 4 from both sides of equation)
(4/8)b - (1/8)b = 84 common denominator on left side
(3/8)b = 84 simplify left side
(8/3)(3/8)b = (8/3)(84) multiply both sides by 8/3
b = (8)(28) reduce fraction by realizing 3 goes into 84 = 28 times
b = 224
