please post each question separately
below is the answer to the first question:
---
y = x + 2
xy = 35
---
xy = 35
x(x + 2) = 35
xx + 2x - 35 = 0
---
the above quadratic equation is in standard form, with a=1, b=2 and c=-35
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 2 -35

---
the quadratic has two real roots at:
---
x = 5
x = -7
---
answer:
using either root works for this problem:
x = 5
y = 7
OR
x = -7
y = -5
