Question

I dont know if what i wrote was right but someone help

Answer 1

x = 12/7

Explanation:

You put: What you should have had is:

13x - 3y = 12 13x - 3y = 12

- x + 3y = 12 + x + 3y = 12

Now that we have that, we can do

14x = 24

Than, divide 24 by 14

x = 24/14

which we can simplify by dividing both by 2

x = 12/7

We can't simplify it down anymore, so this is our answer.
