The initial value equation is 
<h3>How to solve the initial value?</h3>
The equation is given as:

Where
Y(0) = 1
Subtract 2y from both sides in the equation

Rewrite as:

Integrate both sides of the equation

Multiply through by -2

Take the exponent of both sides

Next, we solve for C under the initial condition Y(0) = 1.
This gives

Evaluate
-2 + 3 = C
Solve for C
C = 1
Substitute C = 1 in 

Next, we solve for y

Hence, the initial value equation is

Answer:
a = 25 , b = 14
Step-by-step explanation:
For A
a/5 + 3 = 8
a/5 = 8 - 3
a/5 = 5
Cross multiply
a = 5 * 5
a = 25
For B
3b/7 - 1 = 5
3b/7 = 5 + 1
3b/7 = 6
Cross multiply
3b = 42
b = 42 / 3
b = 14
