To use the elimination method, let's first align the equations: 1. \( 5x - 3y = 8 \) 2. \( 2x + 2y = 16 \) Next, we can multiply the second equation by 1.5 so that the coefficient of \( x \) in the second equation matches that in the first. This gives us: \( 1.5(2x + 2y) = 1.5(16) \) \( 3x + 3y = 24 \) Now we have the two equations: 1. \( 5x - 3y = 8 \) 2. \( 3x + 3y = 24 \) Next, we can add these two equations to eliminate \( y \): \[ 5x - 3y + 3x + 3y = 8 + 24 \] This simplifies to: \[ 8x = 32 \] Dividing both sides by 8 gives: \[ x = 4 \] Now that we have \( x \), let's substitute it back into one of the original equations to find \( y \). Using the second equation: \[ 2x + 2y = 16 \] Substituting \( x = 4 \): \[ 2(4) + 2y = 16 \] This simplifies to: \[ 8 + 2y = 16 \] Subtracting 8 from both sides gives: \[ 2y = 8 \] Dividing both sides by 2 gives: \[ y = 4 \] Thus, the solution to the system of equations is the ordered pair: \[ \boxed{(4, 4)} \]
