0.5(r-12)=0.6r

Solution for 0.5(r-12)=0.6r equation:

Simplifying
0.5(r + -12) = 0.6r

Reorder the terms:
0.5(-12 + r) = 0.6r
(-12 * 0.5 + r * 0.5) = 0.6r
(-6 + 0.5r) = 0.6r

Solving
-6 + 0.5r = 0.6r

Solving for variable 'r'.

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

Add '-0.6r' to each side of the equation.
-6 + 0.5r + -0.6r = 0.6r + -0.6r

Combine like terms: 0.5r + -0.6r = -0.1r
-6 + -0.1r = 0.6r + -0.6r

Combine like terms: 0.6r + -0.6r = 0.0
-6 + -0.1r = 0.0

Add '6' to each side of the equation.
-6 + 6 + -0.1r = 0.0 + 6

Combine like terms: -6 + 6 = 0
0 + -0.1r = 0.0 + 6
-0.1r = 0.0 + 6

Combine like terms: 0.0 + 6 = 6
-0.1r = 6

Divide each side by '-0.1'.
r = -60

Simplifying
r = -60
