Question

$-(2x - 1) = -1 - (-x - 1) + 7x$

Explanation:

Step1: Simplify both sides

Left side: $-(2x - 1)=-2x + 1$
Right side: $-1-(-x - 1)+7x=-1 + x + 1 + 7x=8x$

Step2: Solve for \(x\)

Set simplified sides equal: $-2x + 1 = 8x$
Add \(2x\) to both sides: $1 = 10x$
Divide by \(10\): $x=\frac{1}{10}$

Answer:

\(x = \frac{1}{10}\)
