There is not a given equation nor ordered pair, so it is impossible to answer this question. I apologise.
1. x=5/2
2. x=3/4-3/4y
y belongs R
Answer:

Step-by-step explanation:
The formula of an area of a parallelogram:

b - base
h - height
We have:
base₁ = 9.8 in
base₂ = 10 in
height₁ = 5.6 in
height₂ = h
The area of a parallelogram:
and 
Therefore we have the equation:

Substitute:

<em>divide both sides by 10</em>
