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

Add '-0.9x' to each side of the equation.
1.2 + x + -0.9x = 5.4 + 0.9x + -0.9x

Combine like terms: x + -0.9x = 0.1x
1.2 + 0.1x = 5.4 + 0.9x + -0.9x

Combine like terms: 0.9x + -0.9x = 0.0
1.2 + 0.1x = 5.4 + 0.0
1.2 + 0.1x = 5.4

Add '-1.2' to each side of the equation.
1.2 + -1.2 + 0.1x = 5.4 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + 0.1x = 5.4 + -1.2
0.1x = 5.4 + -1.2

Combine like terms: 5.4 + -1.2 = 4.2
0.1x = 4.2

Divide each side by '0.1'.
x = 42

Simplifying
x = 42
