Hello there! Thank you for asking your question here at Brainly! I will be assisting you with answering this question today, and will be teaching you how to handle it on your own in the future.
First, let's take a look at our problem. "Twice a number and 5 more is 100." Based on this context, we are looking for a specific number to plug in.
To solve for this, I will rewrite the problem. As I do so, I will be writing (in parenthesis) the translation of an equation.
Twice a number (2x) and 5 more (+5) is 100 (=100).
This is our equation. To solve for this, we will need to do some basic algebra. Of course, I will teach you how to handle this on your own in future scenarios.
2x + 5 = 100 To solve for x, we need to isolate 2x, and then divide both sides by 2.
2x + 5 = 100 Subtract 5 from both sides to isolate 2x. 5 - 5 = 0 100 - 5 = 95
We now have the following equation: 2x = 95 Divide both sides by 2 to solve for x.
