Question

Solve each equation.

3(20-b)=36

Answer 1

b=8

Explanation:

3(20-b)=36

60-3b=36

-3b=-24

3b=24

b=8

Answer 2

The answer is:

b = 8

Work/explanation:

To solve, distribute 3 on the left:

`\sf{3(20-b)=36}`

`\sf{60-3b=36}`

Subtract 60 on each side

`\sf{-3b=36-60}`

`\sf{-3b=-24}`

Divide each side by -3

`\sf{b=8}`

Hence, b = 8
