Question

the sum of two number is 4 and the ratio of the two numbers is -3. . what is the product of the two numbers?

Answer 1

-12

Explanation:

let x be the 1st number and y be the 2nd number

x+y = 4

x/y = -3

x = -3y

using substitution

-3y + y = 4

-2y = 4

y = -2

x = -3y

x = -3(-2)

x = 6

-2x6 = -12
