Question

Can some tell me what does x equal?

Answer 1

2x-7 i think i rlly hope it’s right

Answer 2

x=10

Explanation:

A straight line has an angle of 180 degrees. To solve for x we can add all the given angles and set them equal to 180.

`180= 5x-1+9x+8+2x+13`

Then combine all the common factors

`180=16x+20`

And then you can solve for x

`180= 16x+20\\160=16x\\10=x`

To check if x is correct you can plug in 10 to each equation. If all the equations add up to 180, then x is correct

`5(10)-1= 49\\9(10)+8= 98\\2(10)+13= 33\\\\49+98+33=180`
