Four times a number minus twice another number is -16. the sum of the two numbers is -1. find the numbers.

-3 and 2

Step-by-step explanation:

let the first number be x and the second be y

four times a number minus twice another number is -16

4x-2y= -16i

the sum of the two numbers is -1

x+y= -1

x=-1-yii

substitute ii in i

4(-1-y)-2y=-16

-4-4y-2y=-16

-4-6y=-16

collectinglike terms

-6y=-16+4

-6y=-12

y=2

substitutes for y in ii

x=-1-y

-1-2

x=-3
