Let x,y be the two numbers
Four times a number minus other number is -16
4x-y=16......eq1
Sum of the two numbers is -1
X+y=-1.......eq2
We need to solve above equations to get x ,y values

Solve:
We'll use substitution. After moving -1*y to the right, we get:
, or . Substitute that
into another equation:
and simplify: So, we know that y=-4. Since , x=3.

Answer: .
