X=-10 and y=-13
And the reason is that I cancelled the -4y and +4y so if the the sings are different you add if they are the same you subtract here I want to cancel the y so I add in order to cancel them out Which gets rid of it. Now I’m adding 3x to -9x Which equals -6x and when u add 22 and the 38 it equals 60 now you would have
-6x=60
Divide 60 by -6
=-10
So x is -10
To work out y u gonna have to substitute in any equation I chose the first one because it’s positive so
3x-4y=22
3x-10-4y=22
-30-4y=22
Add 30 to both sides.
-4y=52
Divide by -4
Y=-13
