Final answer:
The expression can be simplified by combining like terms: the 'x' terms and the 'y' terms. The resulting simplified form is 8x + 5y + 7. This showcases the skill of simplifying expressions, which is similar to working with linear equations.
Step-by-step explanation:
The expression given in the question, 4x + 2y + 7 + 4x + 3y, is a linear combination that can be simplified by combining like terms. The terms with 'x' can be combined, as can the terms with 'y'. The constant term '7' remains unchanged since there is no other constant to combine it with.
To simplify:
- Combine the 'x' terms: 4x + 4x which equals 8x.
- Combine the 'y' terms: 2y + 3y which equals 5y.
- Keep the constant term: 7.
Therefore, the simplified form of the expression is 8x + 5y + 7.
