The Solution for the given system of equations is (-2) and .
The given are linear equations as follow:
y = + 3 .. ... ...(1)
and x = -2. .. .... ...(2)
We already know the first part of the solution (x) which is -2. We can find the other part (y) by putting the value of equation (2) in equation (1).
By putting the values of x in equation (1), we get
y = + 3
y = + 3
Taking the L. C. M of denominators which will be '3', we get:
y =
y =
So the second part (y) of the solution of the given equation is .
Hence, the overall solution to the given system of equation is .

Answer:
А.The system has two solutions, but only one is viable because the other results in a negative width.
Step-by-step explanation:
Given
Let:
length of play area A
width of play area A
length of play area B
width of play area B
Area of A
Area of B
From the question, we have the following:
The area of A is:
This gives:
Open bracket
The area of B is:
Substitute:
Open brackets
Expand
We have that:
This gives:
Collect like terms
Using quadratic calculator, we have:
or
--- approximated
But the width can not be negative; So:
