To solve the system of equations using substitution, we start with the two equations:

1. $y = 2x + 3$
2. $y = x + 2$

Step 1: Substitute $y$ from the second equation into the first equation.

Since $y = x + 2$, replace $y$ in the first equation:

$x + 2 = 2x + 3$

Step 2: Solve for $x$.

Rearrange the terms to isolate $x$:

$2 - 3 = 2x - x$
