Question

2 ( 1 - × ) + 1 = 3 (× - 3 ) - 2 ×

Answer 1

2 ( 1 - × ) + 1 = 3 (× - 3 ) - 2 ×
2-2x+1=3x-9-2x
-2x-3x+2x=-9-1
-3x=-10  (-1)
3x=10
x=10/3

Answer 2

Olá!!!

2 ( 1 - x ) + 1 = 3 ( x - 3 ) - 2x
2 - 2x + 1 = 3x - 9 - 2x
- 2x - 3x + 2x = - 9 - 1 - 2
- 3x = - 12
x = - 12 / - 3
x = 4

S = { 4 }
