7x + 18 - y + 13(x + y) - y/x
Simplifying the expression:
7x + 18 - y + 13x + 13y - y/x
Combining like terms:
20x + 12y + 18 - y - y/x
Therefore, the simplified expression is:
7x + 18 - y + 13(x + y) - y/x
Simplifying the expression:
7x + 18 - y + 13x + 13y - y/x
Combining like terms:
20x + 12y + 18 - y - y/x
Therefore, the simplified expression is:
20x + 12y + 18 - y - y/x
