Ta có
x + 50 = 100
=) x = 100 - 50
=) x = 50
Ai k mình mình k lại nhé =)))

a) x +60+40 =400
x = 400-40-60
x =300
b) (x+25) + 50 = 100:2 +30
(x+25) +50 = 50+30=80
x+25 = 80-50=30
x =30-25
x = 5
a.x+60+40=200
x+100=200
x=200-100
x=100
b.x+25+50=100:2+30
x+75=50+30
x+75=80
x=80-75
x=5
mk nhanh nhất

a, 30 + x = 50
x = 50 - 30= 20
b, 100 - x = 50
x = 100 - 50 = 50
![](https://rs.olm.vn/images/avt/0.png?1311)
a) x + 100 = 50 + 60
x + 100 = 110
x = 110 - 100
x = 10
b) x + 50 = 30 + 60
x + 50 = 90
x = 90 - 50
x = 40

Tìm x :
x + 100 = 50 + 150
x + 100 = 200
x = 200 - 100
x = 100
Vậy x = 100
x + 100 = 50 + 150
x + 100 = 200
x = 200 -100
x = 100
Đúng 100 %

x + 100 = 100 + 100 x 2 + 400
x + 100 = 100 + 200 + 400
x + 100 = 700
x = 700 - 100
x = 600
Vậy x = 600
x+100=100+100x2 +400
x+100=100+200+400
x+100= 300+400
x+100=700
x =700-100
x =600
Vay x = 600

100 . ( 100 + 100 ) . 100 = 100 . 200 . 100 = 2 000 000
=> x = 2 000 001 ( nếu là số tự nhiên )
100 - x = 50
x = 100 - 50
x = 50
100-x=50
=> x= 100 -50
=> x=50
