Question

Two numbers total 6, and their difference is 4. Find the two numbers.

PLEASE EXPLAIN!! :(

Answer 1

Let x and y be your two numbers. They are unknown for now.

Answer 2

"Two numbers total 6" means that they add to 6. So, x+y = 6

"their difference is 4" means the result after subtraction is 4. That equation is x-y = 4

Answer 3

So you have this system of equations

x+y = 6
x-y = 4

We can use elimination to solve. Add the equations together to get

x+y = 6
x-y = 4
-------
2x+0y = 10


Since 2x = 10, we know that x = ______
