Question

X ÷ 10 + X × 2 + X ÷ 5 = 24 mình cần gấp trong tối nay . Xin cảm ơn

Answer 1

\(x\div10+x\times2+x\div5=24\)

\(\Leftrightarrow x\times\frac{1}{10}+x\times2+x\times\frac{1}{5}=24\)

\(\Leftrightarrow x=\left(\frac{1}{10}+2+\frac{1}{5}\right)=24\)

\(\Leftrightarrow x\times2,3=24\)

\(\Leftrightarrow x=\frac{240}{23}\)

Answer 2

x/10+x*2+x/5=24 

=>2x/15=24-2x

=>x/15=12-x

=>16x/15=24

=>16x=360=>x=45/2

Answer 3

16x/15=12=>16x=180=>x=45/4 nha bn nhầm tí=))
