Question

3x-7 = -1

x=?
what does x equal?

Answer 1

x=2 because if you replace 2 with x and then you multiple 3 times 2 you get 6 and 6-7 would be a negative number and that number is -1 which was your questions solution

Answer 2

3x - 7 = -1 Add 7 to both sides. 3x = 6 Divide both sides by 3. x = 2
