Solving for variable 'y'.

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

Add 'y' to each side of the equation.
-0.6 + 4y + y = 19.4 + -1y + y

Combine like terms: 4y + y = 5y
-0.6 + 5y = 19.4 + -1y + y

Combine like terms: -1y + y = 0
-0.6 + 5y = 19.4 + 0
-0.6 + 5y = 19.4

Add '0.6' to each side of the equation.
-0.6 + 0.6 + 5y = 19.4 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + 5y = 19.4 + 0.6
5y = 19.4 + 0.6

Combine like terms: 19.4 + 0.6 = 20
5y = 20

Divide each side by '5'.
y = 4

Simplifying
y = 4
