Question

y = -x\
y = -5x + 40

Explanation:

Step1: Set the two equations equal

Since both equal \( y \), set \( -x = -5x + 40 \)

Step2: Solve for \( x \)

Add \( 5x \) to both sides: \( -x + 5x = 40 \) → \( 4x = 40 \)
Divide by 4: \( x = \frac{40}{4} = 10 \)

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

Substitute \( x = 10 \): \( y = -10 \)

Answer:

The solution is \( x = 10 \), \( y = -10 \)
