Question

X x 85 + X : 0,2 + X : 0,1 = 2022

Answer 1

`X xx 85 + X : 0,2 + X : 0,1 = 2022`

` X xx 85 + X xx 5 + X xx 10 = 2022`

` X xx ( 85 + 5 + 10) = 2022`

` X xx 100 = 2022`

` X = 2022 : 100`

` X = 20,22`

Answer 2

`x xx85+x:0,2+x:0,1=2022`

`x xx85+x:1/5+x:1/10=2022`

`x xx85+x xx5+x xx10=2022`

`x xx(85+5+10)=2022`

`x xx100=2022`

`=>x=2022:100`

`=>x=20,22`
