Answer: 2.5
We can substitute the value of x in the equation to get the value of y
-5y = 2x
-5y = 2(-1)
-5y = -2
We can now cancel off the negative signs since there are positive sign on both thr sides
5y = 2
y = 5/2
y = 2.5
Therefore the value of y is 5/2 or 2.5

Answer:
y = -2/5
x = 5/2
Step-by-step explanation:
x = -1
-5y = 2x
-5y = 2 * (-1 )
-5y = -2
y = -2/5
y = -1
-5y = 2x
-5 * (-1) = 2x
= 5 = 2x
= 5/2 = x
