Answer 4

i have no idea on this one sorry

Answer 5

@Agent47

Answer 6

the same vertically opposite angles are equal

Answer 7

so
4y - 8 = 79 + y

Answer 8

so 79 is the answer

Answer 9

hmmmm rreally???? how??

Answer 10

i was asking so we - 79 from 87

Answer 11

u wrote 'so 79 is the answer' ??? -_-
and wht do u mean???? :/

Answer 12

i was aking my bad so we subtract 79 from 87

Answer 13

nope why subtract...see u got
4y - 8 = 79 + y
so
4y - y = 79 + 8
3y = 87

Answer 14

@logan13 so whts y ??

Answer 15

\[4y-8=79+y\]
\[3y=87\]
\[\frac{ 3y }{ 3 }=\frac{ 87 }{ 3 }\]
\[y=\frac{ 3*29 }{ 3 }\]
\[y=29\]

Answer 16

is i dont know im trying to ask how we get Y

Answer 17

@alex6799 nicely done :)

Answer 18

wait 29 ?

Answer 19

see to get y u need to solve the equation
4y - 8 = 79 + y
isolate variable on one side of equality and constant on other

Answer 20

and yeah its 29

Answer 21

this why i am failing math

Answer 22

i never get it

Answer 23

@logan13 its all about practice....give more time to maths :))and all will be good :)

Answer 24

its ok i get it and ill be more than happy to help

Answer 25

@alex6799 u wrote u didnt know how to solve this one?

Answer 26

at first i didn't but you put it into an equation and im very good at thos

Answer 27

ooo good work then :))

Answer 28

and now i know how to do it/ what to do
