Question

The sim of two numbers is -21 one number is half of 2 less than 3 times the other number.What are the numbers

Answer 1

the two numbers are -8 and -13

Explanation:

let one number be x

the other number will be (3x - 2)/2

according to the question:

x + (3x - 2)/2 = -21

x + 3x/2 - 1 = -21

2x + 3x - 2 / 2 = -21

5x - 2 = -21 * 2

5x = -42 + 2

5x = -40

x = -40/5 = -8

the other number will be,

3(-8) - 2 / 2 = -24 - 2 / 2 = -26/2 = -13

thus, the required two numbers are -8 and -13
