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
