Pls help 15x-17+3x-11=180

x= or 11.5---

Step-by-step explanation:

First, simplify the equation by adding the like terms.

15x+3x=18x

-17+-11=-28

So, the equation is:

18x-28=180

    +28  +28   <---(Add the 28 to both sides to cancel out the 28 with opposite operations)

18x=208

/18    /18   <---(Divide the 18 as opposite operation to get x by itself)

x=208/18

=104/9

or 11.5---
