<u><em>Answer:</em></u>either y = 4.5
or y = -4.5
<u><em>Explanation:</em></u>To get the solution, we will need to isolate the y on one side of the equation.
<u>This can be done as follows:</u>
4y</span>²<span> = 81
</span>

<span>
y</span>²<span> = 20.25
y = +/- </span>√(20.25)<span>
either y = +</span>√<span>(20.25) = 4.5
or y = -</span>√<span>(20.25) = -4.5
Since there are no restrictions on the value of y, therefore, both answers would be accepted
Hope this helps :)</span>

Step-by-step explanation:
thats what i came up with
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).
Let's rewrite everything that's in parenthesis.
2x + 5 = 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.
2x / 2 = x
95 / 2 = 47.5
x = 47.5
47.5 is your number.
I hope this helps!
