Answer:
U = 
Step-by-step explanation:
Given
T = 
Multiply both sides by E to clear the fraction
TE = 3U ( divide both sides by 3 )
= U
The answer is w + 4 > -12

Answer:

Step-by-step explanation:

DE :
If y is a solution of given DE then it satisfied the DE.
Differentiate w.r.t t

Using the formula

LHS:
RHS

By using the formula

LHS=RHs
Hence, y is a solution of given DE
