Problem #7 Subtract x + 4 from 7x + 1. Problem #8 Subtract 6x - 8 from - 4x + 5. Problem #9 Subtract - 6n + 3 from 4n - 1. Problem #10 Subtract - 8n - 3 from - 4n - 2.

Problem 7: 6x - 3

Problem 8: - 10x + 13

Problem 9: 10n - 4

Problem 10: 4n + 5

Step-by-step explanation:

Problem 7:

Step 1: "Subtract x + 4 from 7x + 1" can be written as:

7x + 1 - (x + 4)

Step 2: Simplifying the expression gives us:

7x + 1 - x - 4 (distribute the negative sign, 'distributive property')

Step 3: Simply the new expression by combining like terms:

7x - x + 1 - 4

6x - 3

Problem 8:

Step 1: "Subtract 6x - 8 from - 4x + 5" can be written as:

-4x + 5 - (6x - 8)

Step 2: Simplifying the expression gives us:

-4x + 5 - 6x + 8 (distribute the negative sign, 'distributive property')

Step 3: Simply the new expression by combining like terms:

-4x - 6x + 5 + 8

-10x + 13

Problem 9:

Step 1: "Subtract - 6n + 3 from 4n - 1" can be written as:

4n + 1 - (-6n + 3)

Step 2: Simplifying the expression gives us:

4n - 1 + 6n - 3 (distribute the negative sign, 'distributive property')

Step 3: Simply the new expression by combining like terms:

4n + 6n - 1 - 3

10n - 4

Problem 10:

Step 1: "Subtract - 8n - 3 from - 4n - 2" can be written as:

-4n - 2 - (-8n - 3)

Step 2: Simplifying the expression gives us:

-4n - 2 + 8n + 3 (distribute the negative sign, 'distributive property')

Step 3: Simply the new expression by combining like terms:

-4n + 8n - 2 + 3

4n + 1
