Q: solve using the addition principle

2x + 6 > x + 16
the solution set is {x|x > ?}

A: {x|x > 10}

To solve the inequality 2x + 6 > x + 16 using the addition principle, we want to isolate the variable x on one side of the inequality.

First, subtract x from both sides of the inequality to get rid of the x term on the right side:
2x - x + 6 > x - x + 16
This simplifies to:
x + 6 > 16

Next, subtract 6 from both sides of the inequality:
x + 6 - 6 > 16 - 6
This simplifies to:
x > 10

Therefore, the solution set is {x | x > 10}. This means that any value of x that is greater than 10 will satisfy the original inequality.
