Answer:
8.15
Step-by-step explanation:
First, let's identify the like terms.
2 and 17
2n and 3n
Next, you would need to combine them. Ex: Add 2n to both sides, and subtract 17 from both sides.
2 - 2n = 3n + 17
2 = 5n + 17
-15 = 5n
Now, all you would need to do is isolate the n. To do this, you would divide both sides by 5.
-15 = 5n
-3 = n
n = -3
The solution would be -3.
I hope this helps!
10x^2 - 25 = x^2
Take the square root of each side.

x = 10x - 5i
