You need to put all terms containing x to the left side and the rest of the numbers to the right side.

To put the terms containing x to the left you should subtract 3x both sides:

2x - 3x + 1 = -2

To put the terms without x to the right side you should subtract 1 both sides:

x = 3

The solution to the equation above is x = 3.
