Answer 1

\(x\times9+x=3,542\times100\)

\(x\times\left(9+1\right)=354,2\)

\(x\times10=354,2\)

\(x=354,2:10\)

\(x=35,42\)

Answer 2

X x 9 + x = 3,542 x 100

X x 10 = 354,2

x = 354,2 : 10

Answer 4

\(x\times9+x=3,542\times100\)

\(x\times\left(9+1\right)=354,2\)

\(x\times10=354,2\)

\(x=354,2:10\)

\(x=35,42\)

Answer 5

X x 9+x=3,542x100

X x 9+X x1=354,2

X x(9+1)    =354,2

X x10        =354,2

X              =354,2 : 10

X              =35,42
