5-5x=16-(6x+2)
Since you can't do anything in the parenthesis get rid of them: 5-5x=16-6x-2
Combine like terms: 5-5x-5=16-6x-2-5..... -5x=9-6x
-5x+6x=9-6x+6x..... 1x=9 or X=9
Check: 5-5(9)=16-(6(9)+2)
5-45=16-(54+2)
-40=16-56
-40=-40 ✔️
I hope this helped, I can explain specific steps better if you'd like :)
