multiplication
28 times x=28x
28x-42=154
add 42 to both sides
28x+42-42=154+42
28x=196
divide both sides by 28
x=7
the number is 7

B = (A - 5hb)/5h This just puts everything over a common denominator.

Step-by-step explanation:

A = 5h (B + b) Divide both sides by 5h

A/5h = B + b Subtract b from both sides.

A/5h - b = B
