Question

4 + x/5 = 5/3 + 1/15

Answer 1

\(4+\dfrac{x}{5}=\dfrac{5}{3}+\dfrac{1}{15}\\ =>4+\dfrac{x}{5}=\dfrac{25}{15}+\dfrac{1}{15}\\ =>4+\dfrac{x}{5}=\dfrac{26}{15}\\ =>\dfrac{x}{5}=\dfrac{26}{15}-4\\ =>\dfrac{x}{5}=\dfrac{-34}{15}\\ =>x=5\cdot\dfrac{-34}{15}=-\dfrac{34}{3}\)

Answer 2

4 + x/5 = 5/3 + 1/15`

`=> 4 + x/5 = 26/15`

`=> x/5 = 26/15 - 4`

`=> x/5 = -34/15`

`=> x =-34/3`

Vậy `x = -34/3`
