6x+15y=-45
<span>6x+5y=-35
subtract second equation from the first
</span>6x+15y=-45
<span>6x+5y=-35
</span><u>- - +
</u> 10y = -10
⇒ y = (-10/10) = 1
put value of y in one of the equation,
6x+5y = -35
⇒ 6x + 5(-1) = -35
⇒ 6x - 5 =-35
⇒ 6x = -35 + 5 = 30
⇒ x = 30/6
⇒ x = 5
So x=5 and y=-1.
Answer:
Hey here’s a trick
A function can’t have more then 1 of the same X but you can have many same y points as you want
so if yous see at least 2 of the same X its automatically not a function
If you see only 1 of each it is a function
just no more then 1 of each x, if you don’t undertsand leave a comment
