Solve for y: 5y - 8 = 17. (4 marks)

Answer 1

To solve the equation \( 5y - 8 = 17 \), follow these steps:

1. Add 8 to both sides to isolate the term with \( y \): \[ 5y - 8 + 8 = 17 + 8 \] This simplifies to: \[ 5y = 25 \]

2. Divide both sides by 5 to solve for \( y \): \[ y = \frac{25}{5} \] This simplifies to: \[ y = 5 \]

Thus, the solution is: \[ \boxed{5} \]
