Answer:
n = 18
Step-by-step explanation:
when you are multiplying, you add the exponents. 2 + x = 20. so by using subtraction we find that x = 18.
Answer: x<4
Given the inequality:

We want to solve the inequality for x.
First, distribute the bracket on the right side of the inequality.

Next, subtract 10x from both sides of the inequality.

Add 24 to both sides of the inequality.

Divide both sides of the inequality by 6.

The solution to the inequality is x<4.
You would multiply 6 by 3 and x by 4. You would end up getting 4x = 18 and then you simplify that to get 9/2 or 4.5.
