Question

Tính:

x+2-3.4:5=2+4-5.2x

Answer 1

x+2-3.4:5=2+4-5.2x

<=> x+2-12/5 = 6 - 10x

<=> 11x =6 - 2 + 12/5

<=> 11x = 32/5

<=> x = 32/55

k mik nha. tks bạn

Answer 2

\(x+2-3.4:5=2+4-5.2x\)
=) \(x+2-\frac{12}{5}=6-10x\)
=) \(x+10x-\frac{12}{5}=6-2\)(CHUYỂN VẾ)
=) \(11x-\frac{12}{5}=4\)
=) \(11x=4+\frac{12}{5}=\frac{32}{5}\)
=) \(x=\frac{32}{5}:11=\frac{32}{55}\)
