Question

[Lê Hoàng Tiến Đạt]

0,75 x X + X : 2 = \(\frac{5}{2}\)

Answer 1

[Edogawa Conan]

\(0,75\times x+x:2=\frac{5}{2}\)

\(0,75\times x+x\times\frac{1}{2}=\frac{5}{2}\)

\(\left(0,75+\frac{1}{2}\right)\times x=\frac{5}{2}\)

                \(1,25\times x=\frac{5}{2}\)

                               \(x=\frac{5}{2}:1,25\)

                                \(x=2\)

Answer 2

[doan thi thuan]

0.75.x+x:2=5/2

0,75.x+x.1/2=5/2

x.(0.75+1/2)=5/2

x.5/4=5/2

x=5/2:5/4=2
