To solve the equation, we need to isolate the variable "u".
Starting with -2 = -2/5u, we can multiply both sides by -5 to get rid of the fraction:
-2(-5) = (-5)(-2/5u)
10 = 2u
Finally, divide both sides by 2 to solve for u:
10/2 = 2u/2
5 = u
Therefore, the solution to the equation -2 = -2/5u is u = 5.
-2 = -2/5u

-5/4t = 9
To solve the equation, we need to isolate the variable "t".
Starting with -5/4t = 9, we can multiply both sides by 4/5 to get rid of the fraction:
(-5/4t)(4/5) = 9(4/5)
-1t = 36/5
Finally, divide both sides by -1 to solve for t:
(-1t)/(-1) = (36/5)/(-1)
t = -36/5
Therefore, the solution to the equation -5/4t = 9 is t = -36/5.
Starting with -5/4t = 9, we can multiply both sides by 4/5 to get rid of the fraction:
(-5/4t)(4/5) = 9(4/5)
-1t = 36/5
Finally, divide both sides by -1 to solve for t:
(-1t)/(-1) = (36/5)/(-1)
t = -36/5
Therefore, the solution to the equation -5/4t = 9 is t = -36/5.
