Question

The sum of two numbers is −63 . One number is 9 less than twice the other number. find the bigger and smaller number

Answer 1

-18 (biggest) and -45.

Explanation:

x + y = -63

y = 2x - 9

Substituting for y in the first equation:

x + 2x - 9 = -63

3x = -63 + 9

3x = -54

x = -18

y = -63 + 18 = -45.
