Write an expression with at least 6 terms

that is equal to 7x+y-4.

(3x + y) + (4x - y) + (-2x + y) + (2x - 2y) + (x + 4) + (-1x - 4)

To write an expression with at least 6 terms that is equal to 7x+y-4, we can break down the given expression into smaller terms.

1. Start with the term 7x, which represents 7 times x: 7x.
2. Add the term y: 7x + y.
3. Subtract 4: 7x + y - 4.
4. Add 0: 7x + y - 4 + 0.
5. Add 0x: 7x + y - 4 + 0x.
6. Add 0y: 7x + y - 4 + 0x + 0y.

Thus, the expression with at least 6 terms that is equal to 7x + y - 4 is:
7x + y - 4 + 0x + 0y.
