6x + 48 + 12x = -12
18x + 48 = -12
18x = -12 - 48 = -60
x = -60/18 = -10/3
6.x+48+12x=-12
x.18=(-12)-48
xx18=-60
x=(-60):18
x=-3,333
6.(x+8)-12x=-12
6.(x+8) + 12x = -12
Tìm x € Z biết:
a) x - (11 - x) = -48 + (-12 + x)
b) (15 - x) + (x - 12) = 7 - (-8 + x)
c) (x - 12) - (2x + 31) = -6 - 5
d) |x + 5| - (-17) = 20 ; 12x2 - 3x = 0
