The middle two. An arithmetic series is when something is added over and over again. Geometric is the same except multiplication. For the first one, it only adds 3. For thr last one, it multiplies by -3. For the middle two, I can't seem to find a pattern.

22+n=11
subreact 22 from both sides
n=11
Ok. first you have to pick x or y or whatever variable you have and the number multiplied with it has to be the same in each equation but one has to be positive and one negative.
lets pick x
y=-2x+6
3y=x-3/ *2
so the x are positive and negative we have to multiply the equation with 2
y=-2x+6
6y=2x-6
now you have to add the equations. you do that by adding each side of the equatins together like this:
y+6y=-2x+6+2x-6 the x will cancel out
7y=0
y=0
now just go back to one of the previous equations and put the y in it.
0=-2x+6
2x=6
x=3
here you go
