For this case we have the following equation:
[tex]5x = 2y[/tex]
To find the value of "x", we use the division equality property, that is, we divide by 5 on both sides of the equation:
[tex]\frac {5x} {5} = \frac {2y} {5}\\x = \frac {2} {5} y[/tex]
Thus, using the mentioned property we have to: [tex]x = \frac {2} {5}y[/tex]
Answer:
[tex]x = \frac {2} {5} y[/tex]
