1. The problem is to solve for $x$ in the equation shown in the image (assuming it is $2x + 3 = 7$). 2. The formula to isolate $x$ is to subtract 3 from both sides and then divide both sides by 2. 3. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 4. Divide both sides by 2: $$\frac{\cancel{2}x}{\cancel{2}} = \frac{4}{2}$$ $$x = 2$$ 5. Therefore, the solution is $x = 2$. This means that when $x$ is 2, the original equation holds true.
