Simplifying
3(y + 7) + 4y = 2y + -3(y + -7) + 8y

Reorder the terms:
3(7 + y) + 4y = 2y + -3(y + -7) + 8y
(7 * 3 + y * 3) + 4y = 2y + -3(y + -7) + 8y
(21 + 3y) + 4y = 2y + -3(y + -7) + 8y

Combine like terms: 3y + 4y = 7y
21 + 7y = 2y + -3(y + -7) + 8y

Reorder the terms:
21 + 7y = 2y + -3(-7 + y) + 8y
21 + 7y = 2y + (-7 * -3 + y * -3) + 8y
21 + 7y = 2y + (21 + -3y) + 8y
