Wdym by animal testing? Like doing experiments on rats as an example?
2x + 3y = 9
x + 5y = 8....multiply by -2
----------------
2x + 3y = 9
-2x - 10y = -16 (result of multiplying by -2)
---------------add
-7y = - 7
y = -7/-7
y = 1
x + 5y = 8
x + 5(1) = 8
x + 5 = 8
x = 8 - 5
x = 3
solution is (3,1)
The y variable stands for the y value in an equation like x+y=1
After the 2 angles the third and fifth line are great
