Answer 1

you need to use algebra.
call the first number x and the second number y.
"The sum of two numbers is -1" would then translate to x + y = -1
"Five times the first number equals 3 times the second number" would translate to 5x = 3y
So you have two equations with two unknowns:
x + y = -1
5x = 3y
You should be able to solve this.

Answer 2

-3/8,-5/8

Answer 3

eq: x+y =-1__________(1) and 5x=3y ______(2);
x=5/3y _______(3);
5/3y+y=-1;
8/3y=-1;
y =-3/8;
substitute y in 3;
-(5/3)*(3/8)
x=-5/8;
