Question

Solve the linear equation: 3(4 + 2b) - b = 27 A b = 15 B b = 5 C b = 3 D b = -3

Answer 1

Multiply the numbers in parentheses by 3.

Which gives you 12 + 6b - b =27

Combine like terms

12 + 5b = 27

Then subtract 12 from both sides

Which leaves you with

5b = 15

Divide both side by 5

which gives you

answer C
