first you should know that x/2 is equaled to 2x/4
so now you can simplify one side of the equation:
2x/4 + 3x/4 + 1 = 5x/4 + 1
now you have:
5x/4 + 1 = -9
so you should add -1 on both sides of the equation
you will have:
5x/4 = -9 -1 ⇒ 5x/4 = -10 ⇒ 5/4 × x = -10 ⇒ x = -10 ÷ 5/4 ⇒ x = -10 × 4/5 = -8
so theanswer is x = -8 :)))
i hope this is helpful
have a nice day
