Solution for 5(r-6)=3[2-(5-r)] equation:


Simplifying
5(r + -6) = 3[2 + -1(5 + -1r)]

Reorder the terms:
5(-6 + r) = 3[2 + -1(5 + -1r)]
(-6 * 5 + r * 5) = 3[2 + -1(5 + -1r)]
(-30 + 5r) = 3[2 + -1(5 + -1r)]
-30 + 5r = 3[2 + (5 * -1 + -1r * -1)]
-30 + 5r = 3[2 + (-5 + 1r)]

Combine like terms: 2 + -5 = -3
-30 + 5r = 3[-3 + 1r]
-30 + 5r = [-3 * 3 + 1r * 3]
-30 + 5r = [-9 + 3r]

Solving
-30 + 5r = -9 + 3r

Solving for variable 'r'.

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