0.18(y-4)+0.12y=0.06y-0.3

Solution for 0.18(y-4)+0.12y=0.06y-0.3 equation:

Simplifying
0.18(y + -4) + 0.12y = 0.06y + -0.3

Reorder the terms:
0.18(-4 + y) + 0.12y = 0.06y + -0.3
(-4 * 0.18 + y * 0.18) + 0.12y = 0.06y + -0.3
(-0.72 + 0.18y) + 0.12y = 0.06y + -0.3

Combine like terms: 0.18y + 0.12y = 0.3y
-0.72 + 0.3y = 0.06y + -0.3

Reorder the terms:
-0.72 + 0.3y = -0.3 + 0.06y

Solving
-0.72 + 0.3y = -0.3 + 0.06y

Solving for variable 'y'.

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

Add '-0.06y' to each side of the equation.
-0.72 + 0.3y + -0.06y = -0.3 + 0.06y + -0.06y

Combine like terms: 0.3y + -0.06y = 0.24y
-0.72 + 0.24y = -0.3 + 0.06y + -0.06y

Combine like terms: 0.06y + -0.06y = 0.00
-0.72 + 0.24y = -0.3 + 0.00
-0.72 + 0.24y = -0.3

Add '0.72' to each side of the equation.
-0.72 + 0.72 + 0.24y = -0.3 + 0.72

Combine like terms: -0.72 + 0.72 = 0.00
0.00 + 0.24y = -0.3 + 0.72
0.24y = -0.3 + 0.72

Combine like terms: -0.3 + 0.72 = 0.42
0.24y = 0.42

Divide each side by '0.24'.
y = 1.75

Simplifying
y = 1.75
