Answer:
C=3
Explanation:
2-4(c-1)=-6
FIRST your going to multiply everything in the parentheses by the outside number which is -4
2-4c+4=-6
SECOND you’re going to combine 2 and 4
2+4-4c=-6
6-4c=-6
THIRD you’re going to substrate 6 from both sides.
6-4c=-6
-6 -6
=
-4c=-12
FOURTH you’re going to divide -4 on both sides to get c alone.
-4c=-12
/-4 /-4
=
c=3
