Answer
$x=-2$
Work Step by Step
Distribute $3$ on the left side of the equation and then combine the like terms:
$$ 5 - (2x - 1) = 10 \\
5 - 2x + 1 = 10\\
6-2x=10 .$$
Combine like terms by subtracting $-6$ to both sides first:
$$
6-2x-6=10-6\\
-2x=4
.$$
Dividing both sides by $-2$, we get that $x=-2$.
