Question

X-y=-6
6x-3y=-9
Can you show the steps please

Answer 1

Explanation:

x-y=-6 (1)..

6x-3y=9 (2)...

First, multiply (1) by 6:

6x-6y=-36

Now subtract the whole eqaution:

6x-6y=-36

- 6x-3y=9

----------------------

-3y = -45

y=15

Now substitute y into one of the equations:

x-15=-6

x=9

So the answer is x=9, and y=15.
