9/2X+18+3X=11/2
First, expess all terms as halves
9/2x + 36/2 + 6/2x = 11/2
Combine "x" terms
15/2x +36/2 = 11/2
Subtract 36/2 from both sides
15/2x = -25/2
Divide both sides by 15/2
x = (-25/2)/(15/2) = (-25/2)(2/15) = -25/15 = -5/3
Try to understand why this works.

Is that (9/2)x or 9/(2x)?

times both sides by 2
9x + 36 + 6x = 11
15x + 36 =11
15x = -25
x = -1.67 (in 2dp)
