Four more than 1/3 of a number is 8. What is the number?

Please explain how you get the answer :)

18 Is the am

Step-by-step explanation:

To solve this we need to break down what each term means.

Two more than would look like x + 2

One-third of a number is 1/3*X or X/3

From this we can say x*1/3 + 2 = 8

To find X, you need to get X alone.

First, subtract 2 from both sides to get rid of the + 2 factor

X*1/3 = 6

Multiple both sides by 3 to resolve the 1/3 factor

X = 6*3 = 18

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
