-2(b-10n)=10(2n-6)

Solution for -2(b-10n)=10(2n-6) equation:

Simplifying
-2(b + -10n) = 10(2n + -6)
(b * -2 + -10n * -2) = 10(2n + -6)
(-2b + 20n) = 10(2n + -6)

Reorder the terms:
-2b + 20n = 10(-6 + 2n)
-2b + 20n = (-6 * 10 + 2n * 10)
-2b + 20n = (-60 + 20n)

Add '-20n' to each side of the equation.
-2b + 20n + -20n = -60 + 20n + -20n

Combine like terms: 20n + -20n = 0
-2b + 0 = -60 + 20n + -20n
-2b = -60 + 20n + -20n

Combine like terms: 20n + -20n = 0
-2b = -60 + 0
-2b = -60

Solving
-2b = -60

Solving for variable 'b'.

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