a) x+(-35)=18
x-35=18
x=18+35
x=53
vậy x=53
b) -2x-(-17)=15
-2x+17=15
-2x=15-17
-2x=-2
x=-2:(-2)
x=1
vậy x=1
x+(-35)=18
x=18-(-35)
x=-17
x+35=18
x+18-(-35)
x=53
a,x+(-35)=18
x=18-(-35)
x=18+35
x=53
Vậy x=53
b,-2x-(-17)=15
-2x=15+(-17)
-2x=-(17-15)
-2x=-2
Vậy x=1
NHỚ TÍCH MK NHA!
x=-2:-2
x=-1
Vậy x=-1
a, x+(-35)=18
x=18-(-35)
x=-17
b, -2x-(-17)=15
-2x=15+(-17)
-x=(-2):2
-x=-1
x=1
đúng 100% luôn
a,x+(-35)=18
=>x=18-(-35)
=>x=53
b,-2x-(-17)=15
=>-2x-=15+(-17)
=>-2x-=-2
=>x=-2:(-2)
=>x=1
a) x + (-35) = 18
x = 18 - (-35)
x = -17
b) -2x - (-17) = 15
-2x = 15 + (-17)
-2x = -2
x = -2 : (-2)
x = 1
a) x + ( -35 ) = 18
=> x = 18 - ( -35 )
x = 18 + 35
=> x = 53.
b) -2x - ( -17 ) = 15
-2x + 17 = 15
=> -2x = 15 - 17
-2x = -2
=> x = 1.
