Answer:

Step-by-step explanation:
Given



Required
The solution
Differentiate

Next, we solve for c1 and c2
implies that; x = 1 and y = 0
So, we have:

--- (1)
implies that: x = 1 and y' = e
So, we have:


--- (2)
Add (1) and (2)


Divide both sided by e

Divide both sides by 2

Substitute
in 

Rewrite as:

Multiply both sides by e

So, we have:



Answer:
6
Step-by-step explanation:
2x - y = 5 also equals 4x - 2y = 10
4x-2y=10
+3x+2y=4
7x = 14
x = 2
2(2) - y = 5
-y = 1
y = -1
so, B. (2,-1)
