To solve the system of equations:
- \( 2x + 8y = 8 \) (Equation 1)
- \( 2x - 4y = -16 \) (Equation 2)
Let's simplify each equation first.
From Equation 1: \[ 2x + 8y = 8 \] Dividing the entire equation by 2: \[ x + 4y = 4 \quad (1) \]
From Equation 2: \[ 2x - 4y = -16 \] Dividing the entire equation by 2: \[ x - 2y = -8 \quad (2) \]
Now we can solve these two simplified equations:
- \( x + 4y = 4 \)
- \( x - 2y = -8 \)
Next, we can substitute \( x \) from Equation (2) into Equation (1).
From Equation (2), we can express \( x \) as:
\[
x = -8 + 2y
\]
Now substitute this into Equation (1): \[ (-8 + 2y) + 4y = 4 \]
Combine like terms: \[ -8 + 6y = 4 \] Add 8 to both sides: \[ 6y = 12 \] Divide by 6: \[ y = 2 \]
Now substitute \( y = 2 \) back into the expression for \( x \): \[ x = -8 + 2(2) \] \[ x = -8 + 4 \] \[ x = -4 \]
So the solution to the system of equations is: \[ (x, y) = (-4, 2) \]
Final answer: \[ \boxed{(-4, 2)} \]
