Question

tìm X

 3x(5xX-1) = 10

 

 

Answer 1

3 x ( 5 x X - 1 ) = 10

( 5 x X - 1 ) = 10 : 3

( 5 x X - 1 ) = \(\frac{10}{3}\)

5 x X = \(\frac{10}{3}+1\)

5 x X = \(\frac{13}{3}\)

x = \(\frac{13}{3}:5\)

x = \(\frac{13}{15}\)

Answer 2

\(3\times\left(5\times x-1\right)=10\)

\(5\times x-1=10:3\)

\(5\times x-1=\frac{10}{3}\)

\(5\times x=\frac{10}{3}+1\)

\(5\times x=\frac{13}{3}\)

\(x=\frac{13}{3}:5\)

\(x=\frac{13}{15}\)

Answer 3

3 * ( 5 * x -1) = 10

5 * x - 1 = 10/3

5* x = 13/3

x = 13/15

Dấu * là dấu nhân

Answer 4

\(3\left(5\cdot x-1\right)=10\)

\(5x-1=\frac{10}{3}\)

\(5x=\frac{10}{3}+1\)

\(5x=\frac{13}{3}\)

\(x=\frac{13}{15}\)

Answer 5

\(3x5\left(5\times x-1\right)=10\)

\(\left(5\times x-1\right)=10\div3\)

\(\left(5\times x-1\right)=\frac{10}{3}\)

\(5\times x=\frac{10}{3}+1\)

\(5\times x=\frac{13}{3}\)

\(x=\frac{13}{3}:5\)

\(x=\frac{13}{15}\)

Answer 6

\(3\times\left(5x-1\right)=10\)

\(\Rightarrow5x-1=10:3\)

\(\Rightarrow5x-1=\frac{10}{3}\)

\(\Rightarrow5x=\frac{10}{3}+1\)

\(\Rightarrow5x=\frac{13}{3}\)

\(\Rightarrow x=\frac{13}{3}:5\)

\(\Rightarrow x=\frac{13}{15}\)

Vậy  \(x=\frac{13}{15}\)
