Solve for b.<br> 3-2(b - 2) = 2 - 7b

malfutka [58]

Answer:

b = -1

Step-by-step explanation:

use distributive property to multiply the -2 with the numbers in the parentheses

3 - 2b + 4 = 2 - 7b

7 - 2b = 2 - 7b

add 2b to both sides

7 = 2- 5b

subtract 2 from both sides

5 = -5b

divide by -5

b = -1
