## Final Answer

Attached a word and pdf files. Let me know if you need more explanations.

1. Simplify the expression 4(x + 1) + 1

2. Solve the equation 4(x + 1) + 1 = -7

3. Explain the difference between solving an equation for a variable and simplifying an

expression.

1.

4( x+1) +1 = 4x + 4 + 1, using distributive property, distribute 4 over to x + 1

= 4x + 5, combining like terms.

The expression is simplified.

2. 4(x +1 ) + 1 = -7

4x + 5 = -7, simplified the left si...
