Question

Solve: −3x − 1 = 8

A. −3

B. 3

C. −2.3

D. 6

Answer 1

Hint: start by adding 1 to both sides

Answer 2

add one to both sides to get -3x by itself then what ever you get when you add 1 to 8, divide that by -3 to get x by itself.

Answer 3

A. you would add one to each side -3x-1=8 would then go to -3x=9 then divide each side by -3 and you get x= -3

Answer 4

-3x = 1 + 8
-3x = 9
x = -3
