Answer 14

Try this, www.wolframalpha.com
It's a computational knowledge engine.(Basically a very big calculator)
You can plug the equation into the engine and you can see the solution.
I would suggest getting the app, it's cheap and it can show the step-by-step solution.

Answer 18

let me check

Answer 19

yup!

Answer 20

6z - 3z - 7 = -2 + 3 ---- combine like terms
3z - 7 = 1
do you understand so far ?

Answer 21

@agl202309 please try this problem on your own. but if not you need to combine .
6z - 3z

Answer 22

yes(sorry my computer is very slow)

Answer 23

add seven on both sides of the equation so that seven cancels out on the left side of the equation so now it would look like this

3z = 1 + 7

Answer 24

now combine the terms on the right side

Answer 25

the terms are 7 and 1 so combine them and you get what?

Answer 26

so it is 8

Answer 27

no..
we now have 3z = 8
now divide both sides by 3

Answer 28

it is indeed 8 but it is

3z = 8

now you need to isolate the z which means dividing it on both sides of the equation

so now it looks like z = 8/3

Answer 29

correct....so if z = 8/3.....that is 1 solution

Answer 30

becuase there are no infinite/none amount of answer s for this one problem.

Answer 31

ok one solution! thanks for helping.
