Answer 1

Hi there!

a)

`2x + 8 = x + 25 + 8`
Collect terms


`2x + 8 = x + 33`
Subtract x


`x + 8 = 33`
Subtract 8


`x = 25`


b)

`3x + 23 = 2x + 59`
Subtract 2x


`x + 23 = 59`
Subtract 23


`x = 26`


c)

`5 + 12 = 17`
This is not an equation, but the sum of 5 and 12 is 17, so it's true.


d)

`2x - 4 = x + 9`
Subtract x


`x - 4 = 9`
Add 4.


`x = 13`


e)

`5x - 10 = 4x - 12`
Subtract 4x


`x - 10 = - 12`
Add 10


`x = - 2`
