Question

A) 23-(x+2)=14 B) 5×(x+12)+22=92 Giúp mình cái

Answer 1

\(\text{a},\left(x+2\right)=23-14\\ \left(x+2\right)=9\\ x=9-2\\ x=7\\ b,5.\left(x+12\right)=92-22\\ 5\left(x+12\right)=70\\ \left(x+12\right)=70:5\\ x+12=14\\ x=14-12\\ x=2\)

Answer 2

`23-(x+2)=14`

`x+2=23-14`

`x+2=9`

`x=9-2`

`x=7`

Vậy `x=7`

_______________________
`5.(x+12)+22=92 `

`5.(x+12)=92-22`

`5.(x+12) = 70`

`x+12=70:5`

`x+12=14`

`x=14-12`

`x=2`

Vậy `x = 2`

Answer 3

A) 23 - (x+2) = 14
            (x+2) = 23 -14
            (x+2) = 9 
             x       = 9 - 2
Vậy x bằng 7

B) 5 x (x+12)+22=92
     5 x (x+12) = 92-22 
     5 x (x+12) = 70
           (x+12) = 70 : 5 
           (x+12) = 14  
Vậy x bằng 2
