594 + 18 x X = 1800
18 x X = 1800 - 594
18 x X = 1206
X = 1206 : 18
X = 67
(chú thích dấu x là dấu .)
594+18 .x=1800
18x=1800-594
18x=1026
x=1026:18
x=67
594+18 × x =1800
18 × x =1800-594
18 × x = 1206
x = 1206:18
x = 67
Vậy x = 67
~bn nào thấy đúg tk mk nha~
549+18.x=1800
18x=1026
x=1206:18
x=67
594 + 18x = 1800
18x = 1800 - 594
18x = 1206
x = 1206 : 18
x = 67
594+18xX=1800
18xX=1800-594
18xX=1206
x=1206:18
x=67
594+18xX=1800
18xX=1800-594
18xX= 1206
