Solution for a=2x-y+(20-1)*(x-y) equation: 


Simplifying
a = 2x + -1y + (20 + -1)(x + -1y)

Combine like terms: 20 + -1 = 19
a = 2x + -1y + (19)(x + -1y)
a = 2x + -1y + (x * 19 + -1y * 19)
a = 2x + -1y + (19x + -19y)

Reorder the terms:
a = 2x + 19x + -1y + -19y

Combine like terms: 2x + 19x = 21x
a = 21x + -1y + -19y

Combine like terms: -1y + -19y = -20y
a = 21x + -20y
