5) Go....

`17 = 4x + 1`

`4x + 1 = 17`

Subtract sides 1

`4x + 1 - 1 = 17 - 1`

`4x = 16`

Divide sides by 4

`(4x)/(4) = (16)/(4) \\`

`x = 4`

_________________________________

6) Go...

`2x - 2 = 16`

Add sides 2

`2x - 2 + 2 = 16 + 2`

`2x = 18`

Divide sides by 2

`(2x)/(2) = (18)/(2) \\`

`x = 9`

7) Go...

`95 = 7x + 18`

`7x + 18 = 95`

Subtract sides 18

`7x + 18 - 18 = 95 - 18`

`7x = 77`

Divide sides by 7

`(7x)/(7) = (77)/(7) \\`

`x = 11`

_________________________________

8) Go...

`78 + 9x - 6 = 180`

`9x + 72 = 180`

Subtract sides 72

`9x + 72 - 72 = 180 - 72`

`9x = 108`

Divide sides by 9

`(9x)/(9) = (108)/(9) \\`

`x = 12`
