Find the x and y of x-3y=15 and -2x-4y=10

Use elimination to create a one variable equation.

 x-3y=15 -> 2x-6y=30

   2x-6y=30

+(-2x-4y=10)

-10y=40

Then solve (for y in this case).

y=-4

Now we can use the value for y to solve for x.

x-3y=15 -> x-3(-4)=15 -> x=3

5/20 so 25%

step-by-step explanation:

a reflection across the x axis and a 90 degree rotation left and right.
