Question

I'm having some trouble understanding this question. please help

Solve for z.

z−49−13=59

Answer 1

Any ideas?

Answer 2

it's supposed to look like this oops z−4/9−1/3=5/9

Answer 3

Ok, what do you think?

Answer 4

do I need to add to both sides?

Answer 5

Yup...

Answer 6

okay, do I add 1/3 to both sides?

Answer 7

You could, but look what you're adding to...

Answer 8

It has a 9 in the denominator, right?

Answer 9

yeah

Answer 10

it's larger than the denominator?

Answer 11

what do you mean?

Answer 12

oops numerator

Answer 13

the denominator is larger than the numerator so it won't work right?

Answer 14

It will work if you make them have the SAME denominators

Answer 15

so add 4 to the 5

Answer 16

yup

Answer 17

ok

Answer 18

so z - 9/9 - 1/3?

Answer 19

nope

Answer 20

um okay. any suggestions then?

Answer 21

I'm not fully understanding

Answer 22

let's start again

Answer 23

z−4/9−1/3=5/9

Answer 24

k so should I add 4/9 to 5/9? or what should I do there?

Answer 25

yes

z−4/9−1/3=5/9

4/9 + z − 4/9 − 1/3 = 5/9 + 4/9

Answer 26

add 4/9 to BOTH sides

Answer 27

ok thank you

Answer 28

what do you get after adding 4/9 to both sides?

Answer 29

z = 4/3

Answer 30

Good, now take that value of z and substitute it into the original equation:

z−4/9−1/3=5/9

to check your work

Answer 31

it's right

Answer 32

Good job :D

Answer 33

thank you!!
