Question

5 x X - 3 x X - 13 = 25

Answer 1

\(5\times x-3\times x-13=25\)

\(x\times\left(5-3\right)-13=25\)

\(x\times2-13=25\)

\(x\times2=25+13\)

\(x\times2=38\)

\(x=38:2\)

\(x=19\)

Answer 2

5xX-3xX-13=25

Xx(5-3)=25+13

Xx2=38

X=38:2

X=19

Answer 3

5 x X - 3 x X - 13 = 25

[ 5 - 3  ] x X = 25 + 13

[ 5 - 3 ] x X = 38

2 x X = 38

X = 38 : 2

X = 19

Answer 4

5 x X - 3 x X - 13 = 25

5 x X - 3 x X = 25 + 13

5 x X - 3 x X = 38

( 5 - 3 ) x X = 38

2 x X = 38

X = 38 : 2 

X = 14

Answer 5

5 x X - 3 x X-13 =25

X x (5-3) -13 = 25

X x 2 = 25+13

 X x2 = 38

X=38:2

X=19

Vậy X=19

Answer 6

5.x-3.x-13= 25

(5-3)x= 25-13

2x= 12

x=12:2

x=6
