Answer:

x=2 and y=-6 aka. (2,-6) which is the point of intersection

Step-by-step explanation:

Use elimination to cancel out y by adding the equations:

5x=10

x=2

Plug x=2 into one of the equations and find y:

2(5)+2y=-2

10+2y=-2

2y=-12

y=-6

Therefore, x=2 and y=-6

Can someone please help me solve number 13?

oksian1 [2.3K]

If an exponent is negative you need to switch it to the other side.

So it would be 54v¼•w⅔

__________

18v⅔•¹¹/³•x5/7

Then you need to simplify it. So you would do 54÷18 to get 3.

NOTE: when you are simplifying it's dividing, so the answer you get goes where the larger number is. So in this case the 3 is where the 54 was.
