0.2b-1=0.5(b+1.2)

Solution for 0.2b-1=0.5(b+1.2) equation:

Simplifying
0.2b + -1 = 0.5(b + 1.2)

Reorder the terms:
-1 + 0.2b = 0.5(b + 1.2)

Reorder the terms:
-1 + 0.2b = 0.5(1.2 + b)
-1 + 0.2b = (1.2 * 0.5 + b * 0.5)
-1 + 0.2b = (0.6 + 0.5b)

Solving
-1 + 0.2b = 0.6 + 0.5b

Solving for variable 'b'.

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

Add '-0.5b' to each side of the equation.
-1 + 0.2b + -0.5b = 0.6 + 0.5b + -0.5b

Combine like terms: 0.2b + -0.5b = -0.3b
-1 + -0.3b = 0.6 + 0.5b + -0.5b

Combine like terms: 0.5b + -0.5b = 0.0
-1 + -0.3b = 0.6 + 0.0
-1 + -0.3b = 0.6

Add '1' to each side of the equation.
-1 + 1 + -0.3b = 0.6 + 1

Combine like terms: -1 + 1 = 0
0 + -0.3b = 0.6 + 1
-0.3b = 0.6 + 1

Combine like terms: 0.6 + 1 = 1.6
-0.3b = 1.6

Divide each side by '-0.3'.
b = -5.333333333

Simplifying
b = -5.333333333
