Given the system of equations what is the solution?
x + 3y = 5
x - 3y = -1

answer choices
-4, -3
2, 1
-2, 3

Lets use elimination

So multiply the bottom by "-1" so when we add the x's and y's and 5..-1
X's will be eliminated so we will have

x+3y=5
-x+3y=1

Add

6y=6
y=1

Now plug Y in any other the equations above to get X'

x+3(1)=5
x+3=5
    -3   -3
x=2
So
(2,1)

The answer is 2 and 1 hope that helps. there is a app on android phones called photo math you take a pic and it shows how to solve the problems. it helps me out a lot

I'm not sure but i think it's 1670km/h
