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

Add '-0.39x' to each side of the equation.
1.6 + 0.35x + -0.39x = 1.56 + 0.39x + -0.39x

Combine like terms: 0.35x + -0.39x = -0.04x
1.6 + -0.04x = 1.56 + 0.39x + -0.39x

Combine like terms: 0.39x + -0.39x = 0.00
1.6 + -0.04x = 1.56 + 0.00
1.6 + -0.04x = 1.56

Add '-1.6' to each side of the equation.
1.6 + -1.6 + -0.04x = 1.56 + -1.6

Combine like terms: 1.6 + -1.6 = 0.0
0.0 + -0.04x = 1.56 + -1.6
-0.04x = 1.56 + -1.6

Combine like terms: 1.56 + -1.6 = -0.04
-0.04x = -0.04

Divide each side by '-0.04'.
x = 1

Simplifying
x = 1
