Answer 1

Answer

x = 20

Explanation

Given linear equation:

$9x+3=7x+43$

Combine the like terms in the given linear equation:

$\begin{gathered} 9x-7x=43-3 \\ 2x=40 \end{gathered}$

Divide both sides by 2

$\begin{gathered} \frac{2x}{2}=\frac{40}{2} \\ x=20 \end{gathered}$

The solution set is x = 20
