Question

Tìm x :

- ( - x + 13 - 142 )  + 18 = 55

Ai nhanh mk tick

Answer 1

- ( -x + 13 - 142 ) + 18 = 55

x - 13 + 142 + 18 = 55

x + 147 = 55

x = 55 - 147

x = -92

Answer 2

-(-x+13-142)=55-18

-(-x+13-142)=37

x-13+142    =37

x+13           =37-142

x+13           =-105

x                 =-105-13

x                 =-118

Vậy x=-118

Answer 3

- ( - x + 13 - 142 ) + 18 = 55

- x + 13 - 142  = 55 - 18

- x + 13 - 142 = 37

- x + 13 = 37 + 142

- x + 13 = 179

- x = 179 - 13

- x = 166

sorry mik nhầm

Answer 5

-(-x+13-142)+18=55

-(-x+13-142)=55-18

-(-x+13-142)=37

=>-x+13-142=-37

    -x+13=-37+142

    -x+13=105

    -x=105-13

    -x=92

=>x=-92

vậy x=-92
