Answer:
x=
or 11.5---
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---
