Step 1:
: Identify the equation and its components.

Here, $$2x$$ is the term multiplied by the variable, $$3$$ is the constant term, and $$7$$ is the target value that the equation should equal after solving for the variable.

Step 2:
: Move all terms containing the variable to one side of the equation and all other terms to the other side.

2x + 3 - 3 = 7 - 3 \Rightarrow 2x = 4
To do this, subtract the constant term from both sides:

Step 3:
: Solve for the variable by isolating it.

\frac{2x}{2} = \frac{4}{2} \Rightarrow x = 2
Divide both sides of the equation by the coefficient of the variable:

Step 4:
: Check the solution by substituting the calculated value back into the original equation.

2(2) + 3 = 7 \Rightarrow 4 + 3 = 7 \Rightarrow 7 = 7
Since both sides of the equation are equal, the solution is correct.

Final Answer

The solution to the equation 2x + 3 = 7 is x = 2.
