-5(x-9)=6x+34 multiply the () first
-5x+45=6x+34 subtract from both sides of =
-34 -34
-5x+11=6x add to both sides of =
+5x +5x
11=11x divide from both sides
11/11=11x/11
1=x
Your check is plugging in 1 for x and you will find 40=40. Good luck with your homework.

First distribute:
-5x + 45 = 6x + 34
Then combine x terms on one side, constant terms on the other
45-34=6x+5x
so
11x = 11
x=1
I hope you can understand those steps so you can do this kind of problem for yourself.

-5(x-9) = 6x +34
-5x +45 = 6x = 34
x= 11
can't you solve that yourself?

multiply:
-5x+45=6x+34
transpose:
-5x-6x=34-45
-11x=-11{divide}
x=1
