.2(y-18)=2.0y

Solution for .2(y-18)=2.0y equation:

Simplifying
0.2(y + -18) = 2.0y

Reorder the terms:
0.2(-18 + y) = 2.0y
(-18 * 0.2 + y * 0.2) = 2.0y
(-3.6 + 0.2y) = 2.0y

Solving
-3.6 + 0.2y = 2.0y

Solving for variable 'y'.

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

Add '-2.0y' to each side of the equation.
-3.6 + 0.2y + -2.0y = 2.0y + -2.0y

Combine like terms: 0.2y + -2.0y = -1.8y
-3.6 + -1.8y = 2.0y + -2.0y

Combine like terms: 2.0y + -2.0y = 0.0
-3.6 + -1.8y = 0.0

Add '3.6' to each side of the equation.
-3.6 + 3.6 + -1.8y = 0.0 + 3.6

Combine like terms: -3.6 + 3.6 = 0.0
0.0 + -1.8y = 0.0 + 3.6
-1.8y = 0.0 + 3.6

Combine like terms: 0.0 + 3.6 = 3.6
-1.8y = 3.6

Divide each side by '-1.8'.
y = -2

Simplifying
y = -2
