6-25.

Solve each equation below for $x$.

1. $2x+x=b$

Combine like terms.

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

2. $2ax+3ax=b$

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

3. $x+ax=b$

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

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