Question

1. x=5 x+y=8

Explanation:

Step1: Substitute \( x = 5 \) into \( x + y = 8 \)

Substitute \( x = 5 \) into the second equation \( x + y = 8 \), we get \( 5 + y = 8 \).

Step2: Solve for \( y \)

Subtract 5 from both sides of the equation \( 5 + y = 8 \), so \( y = 8 - 5 = 3 \).

Answer:

\( x = 5 \), \( y = 3 \)
