Answer 2

So you ultimately want to solve for 'x'

\[\large 5x + 12 = 3x + 128\]

Combine like terms "that is to say...combine the variables...subtract 3x from both sides of this equation"

5x + 12 = 3x + 128
-3x -3x
--------------------
2x + 12 = 128


Now you want to get that 'x' alone...so subtract 12 from both sides

2x + 12 = 128
- 12 -12
--------------
2x = 116

And finally to solve for 'x' you divide both sides by 2

2x = 116
---------
2 2

\[\large x = \frac{116}{2} = \space ?\]
