2. Solve the system by elimination.
Hint: you will get a decimal for one of your coordinates.
4x - 5y = -9
-4x + y = -7
-5y=-9
1y=-7
-4y= -16
y=4

-4x+4=-7
-4x=-11
x=2.75
@axie or anyone did I do this correctly

Question

2. Solve the system by elimination.
Hint: you will get a decimal for one of your coordinates.
	4x - 5y = -9
	-4x + y = -7
-5y=-9
1y=-7
-4y= -16
y=4

-4x+4=-7
-4x=-11
x=2.75

axie · Answer

-5y=-9
1y=-7

can you explain what you did to convert this? i.e. How you got from -5y to 1y

4x - 5y = -9 -4x + y = -7 so the x's cancel out because you have 4x and -4x so then your left with -5y=-9 and -y=-7 because if you have a variable by itslef you put a 1 infront of it

axie · Answer

Wouldn't the one be positive bc the negative cancelled out when you combined the x's.
So I think it would be -5y=-9 AND 1y=-7 then you would combine those two equations. 
Again i might be wrong @timmyspu is that correct?

You are doing it correct @axie

and I did combine them-5 plus 1 is -4y and -9+-7=-16

axie · Answer

OH ok, then you devided both sides by 4 which gave you y=4

yeah and the I plugged 4 into y thats how I got -4x+4=-7

axie · Answer

Ok, so both equations are correct, I was a bit lost, then again i do my math differently, good job!

Way to go @axie and @bella2025
