Question

Solve for x
20 equals 5 - 3/8 x

Answer 1

To solve the equation \( 20 = 5 - \frac{3}{8}x \), follow these steps:

1. Subtract 5 from both sides:
\[
20 - 5 = -\frac{3}{8}x
\]
This simplifies to:
\[
15 = -\frac{3}{8}x
\]

2. Next, multiply both sides by \(-\frac{8}{3}\) to isolate \(x\):
\[
x = 15 \cdot -\frac{8}{3}
\]

3. Calculate the right side:
\[
x = -\frac{120}{3} = -40
\]

Thus, the solution is:
\[
\boxed{-40}
\]
