Question

tìm x (5+x)-9=34

Answer 1

(5+x ) -9=34

(5+x )    =34+9

(5+x )    = 43

x           = 43-5

x           = 38

Answer 2

(5+x)-9=24 <=> 5+x=33 <=> x=28

Vậy x=28

Answer 3

( 5 + x ) - 9 = 34

( 5 + x ) = 34 + 9

( 5 + x ) = 43

x = 43 - 5

x = 38

Answer 4

5 + (x - 9) = 35

x - 9 = 35 - 5

x - 9 = 30

x = 30 - 9

x = 21
