How do you solve 2x + 3 = 7?

To solve 2x + 3 = 7, subtract 3 from both sides, then divide by 2.

First, let's break down the equation step by step. We start with the equation 2x + 3 = 7. Our goal is to isolate the variable x on one side of the equation. To do this, we need to get rid of the constant term on the left side, which is +3. We can achieve this by subtracting 3 from both sides of the equation. This gives us:

2x + 3 - 3 = 7 - 3

Simplifying both sides, we get:

2x = 4

Now, we need to isolate x by getting rid of the coefficient 2. Since 2 is multiplied by x, we do the opposite operation, which is division. We divide both sides of the equation by 2:

2x / 2 = 4 / 2

This simplifies to:

x = 2

So, the solution to the equation 2x + 3 = 7 is x = 2. This means that if you substitute x with 2 in the original equation, both sides will be equal, confirming that our solution is correct.
