Solution for 20(v+1)-4v=4(4v+3)-21 equation: 


Simplifying
20(v + 1) + -4v = 4(4v + 3) + -21

Reorder the terms:
20(1 + v) + -4v = 4(4v + 3) + -21
(1 * 20 + v * 20) + -4v = 4(4v + 3) + -21
(20 + 20v) + -4v = 4(4v + 3) + -21

Combine like terms: 20v + -4v = 16v
20 + 16v = 4(4v + 3) + -21

Reorder the terms:
20 + 16v = 4(3 + 4v) + -21
20 + 16v = (3 * 4 + 4v * 4) + -21
