Question

Tìm x Biết : x:0,25+x;0,5+x+x;0,01=321

Answer 1

\(x:0,25+x:0.5+x+x:0.01=321\)

\(x.\frac{1}{4}+x.\frac{1}{2}+x+x.\frac{1}{100}=321\)

\(x.4+x.2+x+x.100=321\)

\(x\left(4+2+1+100\right)=321\)

\(x.107=321\)

\(x=321:107=3\)

Answer 2

x : ( 0,25 + 0,5 + 1 + 0,01 ) = 321

x : 1,76 = 321

x = 8025 / 44 . tk minhf nha
