3[-x+(2x+1)]=x-1 whay is x?

well tbh, x will always just equal 1 unless it's next to another number.

Step-by-step explanation:

so the answer is x= 2 btw idk just in case ig

3 ( - x + 2x + 1) = x -1 ( add 1 and 2x together)

3 ( x + 1 ) = x- 1. ( -x and + 2x are like terms)

get rid of parentheses. 3x + 3 = x - 1

moved variable (x) to the left hand side and change its sign. 3x - x + 3 = -1 / 3x - x = 1 - 3

2x - 1 - 3

2x = - 4

x= -2
