Solution for 3(2u+1)=5(3-u)+3(u-2) equation:


Simplifying
3(2u + 1) = 5(3 + -1u) + 3(u + -2)

Reorder the terms:
3(1 + 2u) = 5(3 + -1u) + 3(u + -2)
(1 * 3 + 2u * 3) = 5(3 + -1u) + 3(u + -2)
(3 + 6u) = 5(3 + -1u) + 3(u + -2)
3 + 6u = (3 * 5 + -1u * 5) + 3(u + -2)
3 + 6u = (15 + -5u) + 3(u + -2)

Reorder the terms:
3 + 6u = 15 + -5u + 3(-2 + u)
3 + 6u = 15 + -5u + (-2 * 3 + u * 3)
3 + 6u = 15 + -5u + (-6 + 3u)
