x +100 = 500 : 2
x+ 100 = 250
x=250-100
x= 150
x+500= 650
x= 650-500
x= 150
k giúp mik nhé
x + 100 = 500 : 2
x + 100 = 250
x = 250 - 100
x = 150
x + 500 = 600
x = 600 - 500
x = 100
K mk mk k lại
Hứa luôn
a)
x + 100 = 500 : 2
x + 100 = 250
x = 250 - 100
x = 150
Vậy x = 150
b)
x + 500 = 650
x = 650 - 500
x = 150
Vậy x = 150
x+100=500:2
x+100=250
x=250-100
x=150
vay x=150
x+500=650
x=650-500
x=150
vay x =150
