y = 7/(x + 5)
Answers:
First you have to multiply both sides by the dividend which is x+5. So it would be:
5(x+5) =7
Then you would distribute the 5. It would be:
5x+25=7
You'd then subtract 25 from both sides:
5x= - 18
Then you'd divide 5 by both sides:
x= - 3.6
So the ordered pair would be
(-3.6, 5)
how can the value of y be 5 ..when it is 7?
7 is y and 5 is x i did that problem already
y=7(x+5)
5=7x+35
7x=5-35
7x=-30
x= -30/7
um, is the equation 7 over x+5. because that's what it looks like.
edit
if so,
y=7/(x+5)
5=7/(x+5)
5(x+5)=7
5x+25=7
5x=-18
5x/5=-18/5
x=-3.6 or -3 3/5
(-3.6,5)
