X = t - 3, y equals two divided by quantity t plus five

X = t - 3 is also - t = - x - 3 or t=x+3

Substitute it in

y=2/t+5

y=2 / (x+3) + 5

Let y=0 to solve for x

0=2 / (x+3) + 5

-5 = 2 / (x+3)

-10=x+3

-7=x

Now solve for t

t = x+3

t = (-7) + 3

t = - 4

Now we can solve for y

y = 2 / (-4) + 5

y = - 0.5+5

y = 4.5

To check

4.5 = 2 / (-4) + 5

4.5 = - 0.5 + 5

4.5 = 4.5

-7 = - 4 - 3

-7 = - 7

Therefore

x = - 7

y = 4.5

t = - 4
