# How do you solve 7b-20=3b+12?

Mar 25, 2018

$b = 8$

#### Explanation:

Combine like terms first. Subtract $3 b$ from the right side and left side. This makes the equation now read

$4 b - 20 = 12$

Add $20$ on the left and right side to simplify further, creating

$4 b = 32$

Divide both sides by $4$ to get

$b = 8$

$b = 8$

#### Explanation:

$7 b - 20 = 3 b + 12 \rightarrow$ Add 20 to each side

$7 b = 3 b + 32$

$4 b = 32 \rightarrow$ Divide each side by 4

$b = 8$
