Question

Does anyone know how to do these? I'm having a hard time and you guys are very helpful.

Answer 1

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

Answer 2

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
