The teacher will be very surprised to see your correct solution 😉

You have entered [src]

    -5*y    
4*x*---- = 0
     2

$$4 x \left(- \frac{5 y}{2}\right) = 0$$

Simplify

Detail solution

Given the linear equation:

4*x*(-(5/2)*y) = 0

Expand brackets in the left part

4*x5/2y) = 0

Divide both parts of the equation by -10*y

x = 0 / (-10*y)

We get the answer: x = 0
