Question

gaseste x din: (x:0,31)+1,1= 22,5

Answer 1

(x:0.31)+1.1=22.5
x:0.31+1.1=22.5
1/0.31x+1.1=22.5
1/31/100x+1.1=22.5
1×100/31x+1.1=22.5
100/31x=22.5-1.1
100/31x=21.4
x=21.4:100/31x
x=107/5×31/100
x=107×31/5×200
x=3317/500

x=6.634

Answer 2

$(x:0,31)+1,1=22,5$
$x:0,31=22,5-1,1$
$x:0,31=21,4$
$x=21,4*0,31$
$\boxed{x=6,634}$
