We have to solve the equation for x. The equation is:


7x+3=24

Let's subtract "3" from both sides to get:


\begin{gathered} 7x+3=24 \\ \text{ -3 = -3} \\ ------- \\ 7x=21 \end{gathered}

To isolate and solve for x, we divide both sides by 7, shown below:


\begin{gathered} 7x=21 \\ (7x)/(7)=(21)/(7) \\ x=3 \end{gathered}

The correct answer is x = 3
