Question

y = -4x

y = 3x + 28

Explanation:

Step1: Set the two equations equal

Since both equal \( y \), set \( -4x = 3x + 28 \)

Step2: Solve for \( x \)

Subtract \( 3x \) from both sides: \( -4x - 3x = 28 \) → \( -7x = 28 \)
Divide by \( -7 \): \( x = \frac{28}{-7} = -4 \)

Step3: Find \( y \) using \( y = -4x \)

Substitute \( x = -4 \): \( y = -4(-4) = 16 \)

Answer:

The solution is \( x = -4 \), \( y = 16 \)
