Suprime les parenthese,puis réduire les expressions suivantes (5x-2)-(x-10) (3+x)+(2x-8) (5x-6)-(4x-8x-6)-13x (3x+1)-(x-1)

(5x - 2) - (x - 10)
= 5x - 2 - x + 10
= 4x + 8

(3 + x) + (2x - 8)
= 3 + x + 2x - 9
= 3x - 6

(5x - 6) - (4x - 8x - 6) - 13x
= 5x - 6 - 4x + 8x + 6 - 13x
= - 4x

(3x + 1) - (x - 1)
= 3x + 1 - x + 1
= 2x + 2
