Simplify Expressions 07Ffd7

1. **State the problem:** Simplify the given expressions step-by-step. 2. **Expression 1: $5x$** - This is already simplified. 3. **Expression 2: $4 - 3x$** - This is a linear expression and cannot be simplified further. 4. **Expression 3: $5 + 3x - 1$** - Combine like terms: $5 - 1 = 4$ - So, the expression becomes $4 + 3x$ 5. **Expression 4: $x + 1 - x$** - Combine like terms: $x - x = \cancel{x} - \cancel{x} = 0$ - So, the expression simplifies to $1$ 6. **Expression 5: $2$** - This is a constant and already simplified. **Final simplified expressions:** - $5x$ - $4 - 3x$ - $4 + 3x$ - $1$ - $2$
