Solution for 2R-2(R+3)=4[2R-3(2+R)] equation:


Simplifying
2R + -2(R + 3) = 4[2R + -3(2 + R)]

Reorder the terms:
2R + -2(3 + R) = 4[2R + -3(2 + R)]
2R + (3 * -2 + R * -2) = 4[2R + -3(2 + R)]
2R + (-6 + -2R) = 4[2R + -3(2 + R)]

Reorder the terms:
-6 + 2R + -2R = 4[2R + -3(2 + R)]

Combine like terms: 2R + -2R = 0
-6 + 0 = 4[2R + -3(2 + R)]
-6 = 4[2R + -3(2 + R)]
-6 = 4[2R + (2 * -3 + R * -3)]
-6 = 4[2R + (-6 + -3R)]

Reorder the terms:
-6 = 4[-6 + 2R + -3R]

Combine like terms: 2R + -3R = -1R
-6 = 4[-6 + -1R]
-6 = [-6 * 4 + -1R * 4]
-6 = [-24 + -4R]

Solving
-6 = -24 + -4R

Solving for variable 'R'.

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