Since 5 + 9 is 14 you can use ANY expression that has the same final value/ sum
Answer:
A
Step-by-step explanation:
Answer:
I believe it's the third and fourth answers.
Step-by-step explanation:
X + y = 20---- 1
x - y = 8----- 2
From 1+2
2x = 28
x = 14
Substitute x in eq.2
14 -y = 8
y = 6
Ans : x= 14 , y= 6
Step-by-step explanation:
We have

Let's factor the denomiator first,
the denomaitor is a perfect square so we get

Now, we must think of two fractions that

We use a perfect square term for one fraction, then a linear one for the next, because if we set both of the denomiator to the same factor, we would get a inconsistent system.
So right now, we have





so that means that a is



So our equation is
