Solution Steps

Step 1: Solve the second equation for \( y \)

The second equation is: \[ -2x = y + 4 \] Solve for \( y \): \[ y = -2x - 4 \]

Step 2: Substitute \( y \) into the first equation

The first equation is: \[ 4x + 2y = 4 \] Substitute \( y = -2x - 4 \) into the first equation: \[ 4x + 2(-2x - 4) = 4 \]

Step 3: Simplify and solve for \( x \)

Expand and simplify the equation: \[ 4x - 4x - 8 = 4 \] \[ -8 = 4 \] This is a contradiction, which means there is no solution to the system of equations.

Step 4: Determine the correct choice

Since the system has no solution, the correct choice is: \[ \text{C. There is no solution.} \]

Final Answer

C. There is no solution.
