What is a solution to the system of equation
3x-4y=22
-9x+4y=38

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

you would have to sell 24 bracelets.
