Answer :

To solve the given system of equations:
[tex]\[ \begin{cases} \frac{3x - y}{y - 2} = 4 \\ \frac{x + 2y}{2x - y} = 3 \end{cases} \][/tex]
we can follow these detailed steps:

### Step 1: Simplify the equations

1. Simplify Equation 1:
[tex]\[ \frac{3x - y}{y - 2} = 4 \][/tex]
Multiply both sides by [tex]\(y - 2\)[/tex]:
[tex]\[ 3x - y = 4(y - 2) \][/tex]
Distribute the 4 on the right-hand side:
[tex]\[ 3x - y = 4y - 8 \][/tex]
Bring all terms involving [tex]\(y\)[/tex] to one side:
[tex]\[ 3x - y - 4y = -8 \][/tex]
Combine like terms:
[tex]\[ 3x - 5y = -8 \][/tex]

2. Simplify Equation 2:
[tex]\[ \frac{x + 2y}{2x - y} = 3 \][/tex]
Multiply both sides by [tex]\(2x - y\)[/tex]:
[tex]\[ x + 2y = 3(2x - y) \][/tex]
Distribute the 3 on the right-hand side:
[tex]\[ x + 2y = 6x - 3y \][/tex]
Bring all terms involving [tex]\(x\)[/tex] and [tex]\(y\)[/tex] to one side:
[tex]\[ x + 2y - 6x + 3y = 0 \][/tex]
Combine like terms:
[tex]\[ -5x + 5y = 0 \][/tex]
Divide both sides by -5:
[tex]\[ x - y = 0 \quad \text{or} \quad x = y \][/tex]

### Step 2: Substitute [tex]\( x = y \)[/tex] into the first simplified equation

Substitute [tex]\( x = y \)[/tex] into [tex]\(3x - 5y = -8\)[/tex]:
[tex]\[ 3(y) - 5(y) = -8 \][/tex]
Which simplifies to:
[tex]\[ 3y - 5y = -8 \][/tex]
Combine like terms:
[tex]\[ -2y = -8 \][/tex]
Solve for [tex]\( y \)[/tex]:
[tex]\[ y = 4 \][/tex]

### Step 3: Find [tex]\( x \)[/tex] using [tex]\( x = y \)[/tex]

Using [tex]\( x = y \)[/tex]:
[tex]\[ x = 4 \][/tex]

### Step 4: Present the solution

The solution to the system of equations is:
[tex]\[ x = 4, \quad y = 4 \][/tex]

So, the coordinates [tex]\( (x, y) \)[/tex] that satisfy both equations are:
[tex]\[ (4, 4) \][/tex]
