Question

[x + 5] * 19 : 13 = 5,7

Answer 1

(x + 5) · 19 : 13 = 5,7

=> (x + 5) · 19 = 74,1

=> x + 5 = 3,9

=> x = -1,1

Answer 2

(x+5)x19:13=5,7

(x+5)x19     =74,1

x+5             =3,9

x                 =-1,1

Answer 3

\(\left(x+5\right).19:13=5,7\)

\(\left(x+5\right).19=5,7.13\)

\(\left(x+5\right).19=74,1\)

       \(x+5=74,1:19\)

        \(x+5=3,9\)

        \(x=3,9-5\)

        \(x=-1,1\)

        

Answer 4

(x+5) * 19 : 13 = 5,7

(x+5) * 19 = 74,1

x+5 = 3,9

x = 1,1

Answer 5

\(\left(x+5\right)\times19:13=5,7\)

\(\Rightarrow\left(x+5\right)\times19=5,7\times13\)

\(\Rightarrow\left(x+5\right)\times19=74,1\)

\(\Rightarrow x+5=74,1:19\)

\(\Rightarrow x+5=3,9\)

\(\Rightarrow x=3,9-5\)

\(\Rightarrow x=-1,1\)

Vậy x = -1,1
