How do you solve (3x + 1) - (2x - 1) = 1?

$x = - 1$

Explanation:

$\left(3 x + 1\right) - \left(2 x - 1\right) = 1$

Remove the parentheses, being sure to distribute the $- 1$ in the second set of parentheses.

$3 x + 1 - 2 x + 1 = 1$

Combine like terms.

$x + 2 = 1$

Subtract $2$ from both sides.

$x = 1 - 2$

$x = - 1$
