Solving the Equation 2x + 3 = 7

To solve the equation 2x + 3 = 7, we need to isolate the variable x. To do this, we can start by subtracting 3 from both sides of the equation:

[ 2x + 3 - 3 = 7 - 3 ]

This simplifies to:

[ 2x = 4 ]

Then, divide both sides by 2 to solve for x:

[ \frac{2x}{2} = \frac{4}{2} ]

Thus, the solution is:

[ x = 2 ]

So, the value of x that satisfies the equation is 2. This is a fundamental concept in algebra that lays the groundwork for solving more complex equations.
