Question

ai có nick nro thì cho mik nhé

11+11+11+ x + x = 48 - x

tìm x

Answer 1

\(33+2x+x=48\)

\(\Rightarrow3x=15\)

\(\Rightarrow x=5.\)

Vậy \(x=5.\)

Answer 2

11+11+11+x+x=48-x\

33+x.1+x.1=48-x

33+x.(1+1)=48-x

33+x.2=48-x

48-x.2-x.1=33

48-x.(2-1)=33

48-x.1=33

     x.1=48-33

     x.1=15

     tự làm tiếp nhé

Answer 3

33+ x + x = 48 - x

33 + 2x = 48 -x 

33 = 48 - 3x 

3x = 48 - 33 

3x =15

vậy x = 15: 3 = 3

Answer 4

33 + x + x = 48 - x

=33 + 2x = 48 - x

=33 = 48 - 3x

=3x = 15

vậy x = 15 : 3 = 3
