25 + 3*(x-8) = 106

3*(x-8) = 106 - 25 = 81

x - 8 = 81 : 3 = 27

x =  27 + 8

x = 35

25 + 3 * ( x - 8 ) = 106 

3 * ( x - 8 ) = 106 - 25 

3 * ( x - 8 ) = 81 

x - 8 = 81 : 3 

x - 8 = 27 

x = 27 + 8

3.(x-8)=-81

x-8=-81:3

x-8=-27

x=-27+8

x=-19

25 - 3 . ( x - 8 ) = 106

Vậy x = -19

25 - 3 x ( x - 8 ) = 106
