Question

resolva : 5x-(-x+22)=-4 
11x+(-3x+10)=4x+2
11x-(-3x+10)=4x+2

Answer 1

a) 5x - ( - x + 22) = - 4
5x + x - 22 = - 4
6x = - 4 + 22
6x = 18
x = 18/6
x = 3

b) 11x + ( - 3x + 10) = 4x + 2
11x - 3x - 10 = 4x + 2
11x - 3x - 4x = 2 + 10
4x = 12
x = 12/4
x = 3

c) 11x - ( - 3x + 10) = 4x + 2
11x + 3x - 10 = 4x + 2
11x + 3x - 4x = 2 + 10
10x = 12
x = 12/10
x = 6/5
