We'll write the second number as x.
One number is five more than x. The sum of the numbers is -1.
So, we can write the first number as x+5.
We know: x+(x+5)=2x+5, and x+(x+5)=-1.
We write: 2x+5=-1
Subtract 5 from both sides- 2x=-6
Divide both sides by two- x=-3
The second number is x, and the first number is bigger by 5, so the two numbers are 2 and -3.
Let's check- 2+(-3)= 2-3= -1
Hope I helped you!

Y=x+5
X+y=-1
So u have the two equations now. Now u know what y is so substitute that equation for y
X+ (x+5)=-1
Whatever u do to one side u have to do to the other. So subtract 5 from both sides
X+x=-6 which is the same as 2x=-6
Divide both sides by 2
X=-3
So now that u know what x is substitute it into first or second equation to find y
Y=-3+5 which gives you y=2
OR
X+y=-1 so substitute -3 for x and that gives you -3+y=-1. Add three to both sides giving you y=2
