Answer:
-12
Step-by-step explanation:
-(-2a + 13) + (-9a - 2) - (-7a - 3)
Distribute the negative and positive signs inside their respective parentheses.
2a - 13 - 9a - 2 + 7a + 3
Combine like terms.
Combine 2a, -9a, and 7a (by this I mean add them together). Also combine -13, -2, and 3 then rewrite the expression.
The terms with "a" cancel out, so you have 0 in its place.
-13 - 2 + 3 = -12
The final answer is -12.
