X - 100 = 50 x 4
X - 100 = 200
X = 200 + 100
X = 300
X - 100 = 50 x 4
X - 100 = 200
X = 200 - 100
X = 100
X - 100 = 50 x 4
X - 100 = 200
X = 200 - 100
X = 100
x-100=50x4
x-100=200
x =200+100
x =300
làm đúng chưa k cho mình nhé
X - 100 = 50 x 4
X - 100 = 200
X = 200 + 100
X = 300
X - 100 = 50 * 4
X - 100 = 200
X = 200 + 100
X = 300
x-100=50*4
x-100=200
x =200+100
x =300
Vậy x=300
