7(4x−15)=63


(1 point)
x=

Answer 1

To solve the equation \( 7(4x - 15) = 63 \), follow these steps:

1. **Distribute the 7**:
\[
7 \cdot 4x - 7 \cdot 15 = 63
\]
\[
28x - 105 = 63
\]

2. **Add 105 to both sides**:
\[
28x - 105 + 105 = 63 + 105
\]
\[
28x = 168
\]

3. **Divide both sides by 28**:
\[
x = \frac{168}{28}
\]
\[
x = 6
\]

So, the solution is \( x = 6 \).
