Solving for variable 'y'.

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

Add '-0.08y' to each side of the equation.
-1.6 + 0.56y + -0.08y = -1 + 0.08y + -0.08y

Combine like terms: 0.56y + -0.08y = 0.48y
-1.6 + 0.48y = -1 + 0.08y + -0.08y

Combine like terms: 0.08y + -0.08y = 0.00
-1.6 + 0.48y = -1 + 0.00
-1.6 + 0.48y = -1

Add '1.6' to each side of the equation.
-1.6 + 1.6 + 0.48y = -1 + 1.6

Combine like terms: -1.6 + 1.6 = 0.0
0.0 + 0.48y = -1 + 1.6
0.48y = -1 + 1.6

Combine like terms: -1 + 1.6 = 0.6
0.48y = 0.6

Divide each side by '0.48'.
y = 1.25

Simplifying
y = 1.25
