Let's solve the system of equations using the substitution method.

The system of equations is:

1. $2x - 3y = 5$
2. $4x + y = 11$

Step-by-Step Solution:

Step 1: Solve one equation for one variable.

From the second equation $4x + y = 11$, solve for $y$:

$y = 11 - 4x$

Step 2: Substitute the expression for $y$ into the first equation.

Now substitute $y = 11 - 4x$ into the first equation $2x - 3y = 5$:

$2x - 3(11 - 4x) = 5$

Simplify the equation:

$2x - 33 + 12x = 5$

Combine like terms:

$14x - 33 = 5$

Step 3: Solve for $x$.

Add 33 to both sides:

$14x = 38$

Now, divide by 14:

$x = \frac{38}{14} = \frac{19}{7}$

Step 4: Substitute $x = \frac{19}{7}$ back into the expression for $y$.

Substitute into $y = 11 - 4x$:

$y = 11 - 4\left(\frac{19}{7}\right) = 11 - \frac{76}{7}$

Convert 11 into a fraction with denominator 7:

$y = \frac{77}{7} - \frac{76}{7} = \frac{1}{7}$

Final Solution:

$x = \frac{19}{7}, \quad y = \frac{1}{7}$
