Question

10 x X - X x 3,7 = 15,75

Answer 1

10.x - x.3,7 = 15,75

x. ( 10 - 3,7 ) = 15,75

x. 6,3 = 15,75

x = 15,75 : 6,3

x = 2,5

Answer 2

\(10.x-x.3,7=15,75\)

\(\Rightarrow\left(10-3,7\right).x=15,75\)

\(\Rightarrow6,3.x=15,75\).

\(\Rightarrow x=15,75:6,3\)

\(\Rightarrow x=2,5\)

Vậy x = 2,5

Answer 3

\(10\times X-X\times3,7=15,75\)

\(\Rightarrow\left(10-3,7\right)\times x=15,75\)

\(\Rightarrow6\times3\times x=15,75\)

\(\Rightarrow x=15,75:6,3\)

\(\Rightarrow x=2,5\)

\(Kết luận x=2,5\)
