To solve the inequality \( 4(y - 1) < 2 + 7 \), follow these steps:
Simplify the right side: \[ 2 + 7 = 9 \] So the inequality becomes: \[ 4(y - 1) < 9 \]
Distribute \( 4 \) on the left side: \[ 4y - 4 < 9 \]
Add \( 4 \) to both sides: \[ 4y < 9 + 4 \] \[ 4y < 13 \]
Divide both sides by \( 4 \): \[ y < \frac{13}{4} \]
Thus, the solution to the inequality is: \[ y < 3.25 \]
