Answer 3

15xX+19xX=39440

Xx(15+19)=39440

Xx34=39440

X=39440:34

X=1160

Vậy X=1160.

Answer 4

15 X x + 19 X x = 39440

     x X (15+19) =39440

     x X 34          =39440

           x             =\(\frac{39440}{34}\)

           x             =1160

Answer 5

15 . x + 19 . x = 39440

(15 + 19) . x = 39440

34 . x = 39440

x = 39440 : 34

x = 1160
