Question

-1/3x+1=-7 negative one third x plus one equals negative seven

Answer 1

Answer:
x=24

Solving:

-1/3x + 1 = -7
- 1 -1
-1/3x = -8
3(-1/3x) = 3(-8)
-1x = -24
x = 24

Answer 2

Multiply both sides by -3 to get rid of the negative and the fraction.

X - 3 = 21

Move the constants over to isolate the variable

X = 24
