To solve the equation $2x + 3 = 7$, follow these steps:

Step 1: Isolate the term with the variable

We want to isolate the term with $x$ on one side of the equation. To do this, we first eliminate the constant term (the 3 on the left-hand side) by subtracting 3 from both sides of the equation.

$2x + 3 - 3 = 7 - 3$

Simplifying this gives:

$2x = 4$

Step 2: Solve for $x$

Now that we have $2x = 4$, we solve for $x$ by dividing both sides of the equation by 2:

$\frac{2x}{2} = \frac{4}{2}$

Simplifying this gives:

$x = 2$

Final Answer:

The solution to the equation is $x = 2$.
