1. The problem is to solve for $x$ given the equation $2x + 3 = 7$. 2. Start by isolating $x$ on one side of the equation. Subtract 3 from both sides: $$2x + 3 - 3 = 7 - 3$$ $$2x = 4$$ 3. Now, divide both sides by 2 to solve for $x$: $$\frac{2x}{2} = \frac{4}{2}$$ $$x = 2$$ 4. Therefore, the solution is $x = 2$.
