To simplify the given algebraic expression:
35x - 11y - 9 + 20x - 1 - y
1. Combine like terms (terms with the same variables):
35x + 20x = 55x
-11y - y = -12y
-9 - 1 = -10
2. Now, rewrite the expression with the simplified terms:
55x - 12y - 10
Therefore, the simplified result of the given expression is:
55x - 12y - 10
