To solve the equation \( 7(4x - 15) = 63 \), follow these steps:
-
Divide both sides by 7 to simplify: \[ 4x - 15 = 9 \]
-
Add 15 to both sides to isolate the term with x: \[ 4x = 9 + 15 \] \[ 4x = 24 \]
-
Divide both sides by 4 to solve for x: \[ x = \frac{24}{4} \] \[ x = 6 \]
The solution is \( x = 6 \).
