Answer:
(14, -2)
Step-by-step explanation:
To solve by using substitution, begin by solving for a variable in the first equation. Let's solve for x:

Now we know what <em>x</em> equals. Let's substitute this into the second equation:

We can then simplify:
Given equation
Combine y terms
Add 2
Divide by -11
So, we now know the value of y = -2.
To find the value of X, we can substitute the value of Y into one of the equations. Let's use the first one:

Substitute for y
Distribute 8
Add 16
So, we now know the value of x = 14.
Therefore, we know a solution to the system of equations is (14, -2).
A. The LCD is (n+1)(n-2)
B. n = -1, n = 2
C. n = negative 1 plus or minus the square root of 73, everything divided 2.
I’ve add a picture of the answers at the bottom in case I wasn’t clear on question C.
Hope that helps.
