Hi there!

a)
[tex]2x + 8 = x + 25 + 8[/tex]
Collect terms

[tex]2x + 8 = x + 33[/tex]
Subtract x

[tex]x + 8 = 33[/tex]
Subtract 8

[tex]x = 25[/tex]


b)
[tex]3x + 23 = 2x + 59[/tex]
Subtract 2x

[tex]x + 23 = 59[/tex]
Subtract 23

[tex]x = 26[/tex]


c)
[tex]5 + 12 = 17[/tex]
This is not an equation, but the sum of 5 and 12 is 17, so it's true.


d)
[tex]2x - 4 = x + 9[/tex]
Subtract x

[tex]x - 4 = 9[/tex]
Add 4.

[tex]x = 13[/tex]


e)
[tex]5x - 10 = 4x - 12[/tex]
Subtract 4x

[tex]x - 10 = - 12[/tex]
Add 10

[tex]x = - 2[/tex]
