Question

tìm x biết: 

x:0.25+x.11=24

Answer 1

Ta có:

\(x:0,25+x.11=24\)

\(x.4+x.11=24\)

\(x\left(4+11\right)=24\)

\(x.15=24\)

\(x=1,6\)

Answer 2

\(x:0,25+x.11=24\)

<=> \(x:\frac{1}{4}+x.11=24\)

<=> \(x.4+x.11=24\)  <=> \(x.\left(4+11\right)=24\)

                                                 <=> \(15x=24\) <=>\(x=\frac{24}{15}\)

vậy \(x=\frac{24}{15}\)

Answer 3

x : 0,25+x.11=24

x × 100/25 + x . 11 = 24

x × 4 + x .11 = 24

x × ( 4+11)=24

x × 15 = 24

x = 24 : 15

x = 1,6

Answer 4

x : 0,25 + x. 11 = 24

x: 1/4 + x.11 = 24

x.4 + x . 11 = 24

x.(4+11) = 24

x.15 = 24

x = 24 : 15 

x = 8/5
