Answer:
To solve the equation \(21 - 2x = 8x + 5\), follow these steps:
1. Combine like terms involving \(x\) on one side of the equation. Add \(2x\) to both sides:
\[
21 = 10x + 5
\]
2. Isolate the term with \(x\) by subtracting 5 from both sides:
\[
16 = 10x
\]
3. Solve for \(x\) by dividing both sides by 10:
\[
x = \frac{16}{10} = 1.6
\]
So, the solution is \(x = 1.6\).
