Thanks in advanced.

Answer 1

do you see small red arrow marks on two lines ?

Answer 2

wat do they tell about the lines ?

Answer 3

Yes I do. That means they are parallel?

Answer 4

Yes !!

those two horizontal lines are parallel

Answer 5

and the cutting vertical lines are transversals

Answer 6

use this :-
same side interior angles add up to 180

Answer 7

(x+30) + 4x = 180
solve x

Answer 8

does that make some sense ? :)

Answer 9

So I add x + 30 and it becomes 30x?

Answer 10

No,
you cant add apples and coconuts !

Answer 11

Add x + 4x?

Answer 12

Yes :)

Answer 13

Sorry I am not good with math but thats why I am here. So I can learn.

Answer 14

you're good, i can see....

Answer 15

(x+30) + 4x = 180

combine like terms

x + 4x + 30 = 180

Answer 16

simplify

Answer 17

and solve x

Answer 18

Thank you. So that becomes 4x + 30 = 180? Then subtract 30 from each side to get 4x = 150?

Answer 19

exactly !!

Answer 20

after that divide 4 both sides, to get the x

Answer 21

Division property of equality to get 37.5?

Answer 22

Answer 23

wait a second,

Answer 24

(x+30) + 4x = 180

combine like terms

x + 4x + 30 = 180

5x + 30 = 180

5x = 150

x = 10

Answer 25

we should get x=10

Answer 26

And do I even worry about the 5x - 25 or do I do the same thing above just with x + 30 and the 5-25?

Answer 27

we dont need to worry about that :)

Answer 28

make sure, you see u get x = 10

Answer 29

So the x in x + 30 is 1 then add that to 4x gets 5x?

Answer 30

Exactly !!

Answer 31

\(x\) is same as \(1x\)

Answer 32

Cool! Alot easier than I thought. Thank you so much! And Im not sure how to give a medal to you.
