Question

The sum of two numbers is ­-10. Negative three times the first number minus the second number equals 2. Find the numbers.

Answer 1

x + y = -10
-3x -y = 2
We'll try with x as a small number and y with a big number to try and balance it out.
-3 - 7 = 10
9 - 7 = 2
X = -3
Y = -7
Hope this helps! :)
