7-25.
1. Solve each equation below for x. Homework Help ✎

1. 2x + x = b

2. 2ax + 3ax = b

3. x + ax = b

Combine like terms.

$\textit{x}=\frac{\textit{b}}{3}$

Combine like terms. Then divide both sides by 5a to solve for x.

Factor out an x on the left side. Solve for x by dividing.

$\textit{x}=\frac{\textit{b}}{1+\textit{a}}$
