Algebra 2 Help! Please!

x-9=2x+10

x-4=2x+5

x-1=2x+2

x-3+2x+4

x-6=2x+7

2x-x = -10-9
x = -19

2x-x = -5-4
x = -9

x-1 = 2x+2
2x-x = -2-1
x = -3

So basically, x = -y-z when in the form: x-y = 2x+z

I'm only going to do one but it's pretty easy :)
x-9=2x+10
x=2x+19 Add 9 to both sides
-x=19 subtract 2x to both sides
x= -19 divide each side by -1

-19 is the answer

1/
-9 - 10 = 2x - x
-19 = x

the rest is similar
