Question

Equação x- [x - (2 - x ) - 1 ]= - (1 - x)

Answer 1

x- [x - (2 - x ) - 1 ]= - (1 - x)
x-[x-2+x-1] = -1+x
x-[2x-3] = -1+x
x - 2x +3 = -1 +x
-x+3= -1+x
-2x=-4               x(-1)
2x=4
x=4÷2
x=2

Answer 2

x - [x - (2 - x) - 1] = - (1 - x)
x - [x - 2 - x - 1] = - 1 - x
x - x - 2 - x - 1 = - 1 - x
- 2 - x - 1 = - 1 - x
-3 - x = -1 - x
-x +x = -1 +3
ox= 2
x=0
