ban Tokisaki Kurumi tính sai bét nhưng nhớ k cho mình nha
Tìm x :
a ) x + 130 - 200 = 300 : 6
x + 130 - 200 = 50
x + 130 = 50 + 200
x + 130 = 250
x = 250 - 130
x = 80
Vậy x = 80
b ) x + 300 = 200 x 2
x + 300 = 400
x = 400 - 300
x = 100
Vậy x = 100
Tìm x :

a) x+130-200=300:6
=x-70=50
=>x =50+70
=>x=120
b) x+300=200*2
x+300=400
x=400-300
