-2 / 5y = 4

Multiply both sides by 5y:

-2/ 5y * 5y = 4 * 5y

refine: -2 = 20 y

Switch sides:

20 y = - 2

Divide both sides by 20

20 y / 20 = - 2 / 20

y = -1/10

hope this helps!

If you would like to solve the equation -2/5 * y = 4, you can do this using the following steps:

-2/5 * y = 4
2/5 * y = -4
y = -4 * 5/2
y = -20/2
y = -10 

The correct result would be -10.
