We can solve this by setting up a system of equations. x and y will represent the two numbers.
x+y = 12
x-y = -2
Personally, I'm going to solve the system by solving one of the equations for x and substituting it into the other one.
x = 12-y
12-y-y = -2
12-2y = -2
-2y = -14
y = 7

Now find the other number by plugging 7 in for y in one of the equations.
x+7 = 12
x = 5
OR
x-7 = -2
x = 5

So, the two numbers are 5 and 7.

-6x+6y=6<br> -6x+3y=-12<br> How do you solve this problem?
sergij07 [2.7K]

Answer:

That's called system of equations. it is like adding and subtracting.

Step-by-step explanation:

first you want to find x or y. i will choose x. in order to do that you need to put one, ill do the first one but you can do first or second, and change it to negative (-6x+6y=6) or -(-6x+6y=6), changing it to 6x - 6y = -6. then the two x's will be cancled since 6-6 is 0. now you add 6y and 3y, and 6 with -12. get your answer, and do the same thing to y, too. sorry if its a bit confusing, took me a while to learn it too. this is highschool stuff so thats why you will although im im middle too!
