2-104.

Write the equation. 3*x* + (−1) − 1 = *x* + (−3) − 5

One strategy is to flip all of the subtraction terms into the addition area and then simplify.

3*x* + (−1) + (−1) = *x* + (−3) + (−5)

3*x* + (−2) = *x* + (−8)

*x* = −3

Rewrite the equation with the known value of *x* substituted in for *x*.
