To solve for \( y \) in the equation \( 2 (3y - 7) = 34 \), follow these steps:
-
Distribute the 2 on the left side: \[ 2 \cdot 3y - 2 \cdot 7 = 34 \] This simplifies to: \[ 6y - 14 = 34 \]
-
Add 14 to both sides of the equation: \[ 6y - 14 + 14 = 34 + 14 \] Which simplifies to: \[ 6y = 48 \]
-
Divide both sides by 6 to isolate \( y \): \[ y = \frac{48}{6} \] Simplifying this gives: \[ y = 8 \]
Thus, the solution is: \[ y = 8 \]
