Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.
3.2 + 2.8x + x = 3.3 + -1x + x

Combine like terms: 2.8x + x = 3.8x
3.2 + 3.8x = 3.3 + -1x + x

Combine like terms: -1x + x = 0
3.2 + 3.8x = 3.3 + 0
3.2 + 3.8x = 3.3

Add '-3.2' to each side of the equation.
3.2 + -3.2 + 3.8x = 3.3 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0
0.0 + 3.8x = 3.3 + -3.2
3.8x = 3.3 + -3.2

Combine like terms: 3.3 + -3.2 = 0.1
3.8x = 0.1

Divide each side by '3.8'.
