2.Simplifying
12 = 0.5a
Solving
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-0.5a' to each side of the equation.
12 + -0.5a = 0.5a + -0.5a
Combine like terms: 0.5a + -0.5a = 0.0
12 + -0.5a = 0.0
Add '-12' to each side of the equation.
12 + -12 + -0.5a = 0.0 + -12
Combine like terms: 12 + -12 = 0
0 + -0.5a = 0.0 + -12
-0.5a = 0.0 + -12
Combine like terms: 0.0 + -12 = -12
-0.5a = -12
Divide each side by '-0.5'.
a = 24

1. Simplifying
27 = -0.9r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '0.9r' to each side of the equation.
27 + 0.9r = -0.9r + 0.9r
Combine like terms: -0.9r + 0.9r = 0.0
27 + 0.9r = 0.0
Add '-27' to each side of the equation.
27 + -27 + 0.9r = 0.0 + -27
Combine like terms: 27 + -27 = 0
0 + 0.9r = 0.0 + -27
0.9r = 0.0 + -27
Combine like terms: 0.0 + -27 = -27
0.9r = -27
Divide each side by '0.9'.
r = -30
