Multiply the first equation by 2:
4x+10y=8
Subtract the second equation from this so the 4x cancels:
3y = -3
y = -1
Plug into first equation:
2x -5 = 4
2x = 9
x = 9/2 = 4 1/2 = 4.5
So (x,y) = (-1,4.5)
Well a right angle is 90° so all u have to do is take 10° away from that

Hey there!
ANSWER: 
EXPLANATION:
To find the answer to your question, you will need to add.

First, multiply the denominator.

So the denominator will be 20.
Now move on to the numerator. Multiply 5 by 3.

Now multiply 4 bu 2.

If you want to get the numerator, add what you got after multiply.

The numerator is 23. So now let's complete the fraction.

This is your answer!
Hope this helps!
