Answer:
c=a+b-180
Step-by-step explanation:
Since the equation is a+b-c=180, you subtract a and b from both sides, meaning it would be -c=-a-b+180, then you must multiply both sides by -1, and the answer would come out to c=a+b-180.
3(x + 6) = x - 2
3(-4+6)= -4-2
mutiply the bracket by 3
(3)(-4)= -12
(3)(6)= 18
-12+18= -4-2
6= -4-2
6= -6
