4z - 1 ( for now skip the z part) = 3z.
3z times 2 = 6z
Now on the other side, add the 3 outside of the parentheses to the 2 on the inside... you'll get 5 + z
To make each side equal... 5 + ? = 6
Obviously 1... So z = 1
Ok so keep in mind, we are solving for x or z. We want to get it by itself.
So, with 6x= 5x+22, we need to subtract 5x from both sides of the = sign
So 6x - 5x = 1x.
Our new equation looks like 1x= 22
We still don't have x alone so we need to divide one on both sides of the =
Our new and final answer is x=22
