QuestionCoveBot:

We know that 5x-5 angle is not 90 degrees or less...

crispyrat:

so 5x-5+2x+10=180, can you do that from there?

xXQuintonXx:

huh

QuestionCoveBot:

@crispyrat It's finding X.

QuestionCoveBot:

And your gonna confuse Quinton, so I suggest you let me do this.

xXQuintonXx:

lol i've been doing so much hw and stuff today that im getting confused so easilly

crispyrat:

so to find an equation you have to get it so that one side is all x and one side is all numbers ok so for example 5x+2=10 then you minus 2 from both sides 5x=8 and divide 5 by both sides so x=5/8. can u do something similar

@xxquintonxx did you know that a straight line equals 180 degrees?

yea

ik all the degree stuff im just confused on how to find X

snowflake0531:

So since we know that a straight line is 180 degrees, and we have a straight line, we put 180 at one end of the equation, and the other stuff at the other end

snowflake0531:

So we have 180 = 5x-5 +2x+10

snowflake0531:

So what do you get

xXQuintonXx:

13x?

snowflake0531:

@xxquintonxx wrote:
13x?
how did you get that

snowflake0531:

WE want to combine the like terms 180 = 5x-5 +2x+10 180 = (5x+2x) + (10-5)

xXQuintonXx:

my head was completly doing this wrong mb

snowflake0531:

... so what do you get

xXQuintonXx:

so 7x + 5

snowflake0531:

Yes so 180 = 7x + 5 so find x do you know how to do that? i'm not sure about when you earlier said you need help finding x as in finding the equation or the steps to solve for x

xXQuintonXx:

dont i just multiply sum with 7 to get it so that its 5 away from 180 so that i can add the 5?

snowflake0531:

No

crispyrat:

so if you wanted to get rid of 5 on just 7x+5 what would you do

xXQuintonXx:

i'd subtract it by 5 to get rid of it

snowflake0531:

To get rid of the 5 180 = 7x + 5 180 - 5 = 7x + 5- 5

so what do you get

xXQuintonXx:

0

THe whole equation i mean

crispyrat:

no what do u get from 7x+5-5 and 180-5?

xXQuintonXx:

huh

xXQuintonXx:

ima be honest rn, both of u doing this at once got me confused

snowflake0531:

Subtract from both sides of the equation

snowflake0531:

what is 180-5 what is 7x + 5-5

xXQuintonXx:

175 7x

snowflake0531:

Yes so now divide 175/7

xXQuintonXx:

25

snowflake0531:

So there's your answer

xXQuintonXx:

thx
