Question

Como se monta essa conta 2. (X-2)-3. (1-x)=20-(x-4)

Answer 1

2.(x - 2) - 3.(1 - x) = 20 - (x - 4)

2x - 4 - 3 + 3x = 20 - x + 4

5x - 7 = - x + 24

6x = 31

x = 31 / 6

Answer 2

2.(x - 2) - 3.(1 - x) = 20 - (x - 4)

2x - 4 - 3 + 3x = 20 - x + 4

2x + 3x + x = 20 + 4 + 4 + 3

5x + x = 24 + 7

6x = 31

x = 31/6
