Putting this into an equation, it would be (12 ÷ -3) + - (14 x 4)
-4 + -56 = -60

The answer is b2 = 2A/h - b1
A = 1/2(b1 + b2)h
Multiply both sides by 2:
2 * A = 2 * 1/2(b1 + b2)h
2A = (b1 + b2)h
Divide both sides by h:
2A/h = (b1 + b2)h/h
2A/h = b1 + b2
Subtract b1 from both sides:
2A/h - b1 = b1 + b2 - b1
2A/h - b1 = b2
