If 3(b – 20) = -(6 - 12), what is the value of b?

b = 22

Step-by-step explanation:

3 (b - 20) = - (6 - 12)

step 1: distribute the 3 on the left to all the numbers in the parentheses on the left

3b - 60 = - (6 - 12)

step 2: distribute the negative to all the numbers in the parentheses on the right

3b - 60 = -6 +12

step 3: add -6 and 12

3b - 60 = 6

step 4: add 60 to both sides, the 60 on the left will cancel out

3b = 66

step 5: divide 66 by 3

b = 22
