Question

X x 2.8 + X  x5.2 = 48

Answer 1

\(x\times2,8+x\times5,2=48\)

\(x\times\left(2,8+5,2\right)=48\)

\(x\times8=48\)

\(x=48:8\)

\(x=6\)

Answer 2

X x 2,8 + X x 5,2 = 48

X x ( 2,8 + 5,2 ) = 48

X x 8 = 48

      X = 48 : 8

      X = 6

Answer 3

 x * 2,8 + x * 5,2 = 48

 x * (2,8 + 5,2) = 48

 x * 8 = 48

 x = 48 : 8

 x = 6
