Question

3. 1x – 3y = 24
3x + 1y = 12
What’s the (0,0) and how did I get there

Answer 1

(6, -6)

Explanation:

Let's do a process of elimination. Multiply the 2nd equation by 3 so system of equations will now look like this:

x - 3y = 24

9x + 3y = 36

Add these two together to get rid of the y terms and we get

10x = 60 or x = 6

Substitute this value of x into either equation and you will get

3(6) + y = 12 ---> y = -6
