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

Add '-1x' to each side of the equation.
1 + -1x = 0.72 + x + -1x

Combine like terms: x + -1x = 0
1 + -1x = 0.72 + 0
1 + -1x = 0.72

Add '-1' to each side of the equation.
1 + -1 + -1x = 0.72 + -1

Combine like terms: 1 + -1 = 0
0 + -1x = 0.72 + -1
-1x = 0.72 + -1

Combine like terms: 0.72 + -1 = -0.28
-1x = -0.28

Divide each side by '-1'.
x = 0.28

Simplifying
x = 0.28
