Question

Find two integers whose sum is 11 and product is 18

Answer 1

Answer:

x + y = 18

x - y = 11

x = 11 + y

Substitute for the first equation:

x + y = 18

(11+y) + y = 18

11 + 2y = 18

2y = 7

y = 3.5

11 + y = x

11 + 3.5 = x

x = 14.5

Check:

14.5 + 3.5 = 18

14.5 - 3.5 = 11

Both sentences are true, so the numbers are 14.5 and 3.5
