X+33=15+25

=>X+33=40

=>X=40-33

=>X=7

Vậy: X=7

x+33=15+25

x+33=40

        x=40—33  

        x=7

X+33=15+25

X+33= 40

X      = 40-33

X       = 7

Vậy x=7

Ai tích mik, mk tích lại

 nhớ nha*********

\(x+48=78\)

\(x=78-48\)

\(x=30\)

t i c k mình nha

x + 48 = 78

x = 78 - 48

x = 30

Vậy x = 30

x=78-48

x=30

95+105=x+10^2

200=x+100

x=200-100

x=100

ket qua bang 100

95+105=x+10²

=>x+10²=200

=>x+100=200

=>x=200-100

=>x=100

x+10=20

x=20-10

x=10

\(x+10=20\)
