Answer 1

Answer:

X + Y = 7

X = 7 - Y

Now

XY = 10

(7-Y)Y = 10

7Y - Y² = 10

Y²- 7Y + 10 = 0

Y² - 5Y - 2Y + 10 = 0

Y(Y - 5) - 2(Y - 5) = 0

(Y - 2)(Y - 5) = 0

Y = 2, 5

If Y = 2, X = 7 - 2 = 5

If Y = 5, X = 7 - 5 = 2

Answer 2

Answer:x = 5 and y = 2

Step-by-step explanation:so x + y = 7

                                           and x X y = 10

now x as 5 and y as 2 is 5 + 2 = 7

and                                    5 x 2 = 10
