0.3(b-18)=0.6b

Solution for 0.3(b-18)=0.6b equation:

Simplifying
0.3(b + -18) = 0.6b

Reorder the terms:
0.3(-18 + b) = 0.6b
(-18 * 0.3 + b * 0.3) = 0.6b
(-5.4 + 0.3b) = 0.6b

Solving
-5.4 + 0.3b = 0.6b

Solving for variable 'b'.

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

Add '-0.6b' to each side of the equation.
-5.4 + 0.3b + -0.6b = 0.6b + -0.6b

Combine like terms: 0.3b + -0.6b = -0.3b
-5.4 + -0.3b = 0.6b + -0.6b

Combine like terms: 0.6b + -0.6b = 0.0
-5.4 + -0.3b = 0.0

Add '5.4' to each side of the equation.
-5.4 + 5.4 + -0.3b = 0.0 + 5.4

Combine like terms: -5.4 + 5.4 = 0.0
0.0 + -0.3b = 0.0 + 5.4
-0.3b = 0.0 + 5.4

Combine like terms: 0.0 + 5.4 = 5.4
-0.3b = 5.4

Divide each side by '-0.3'.
b = -18

Simplifying
b = -18
