Answer:

Step-by-step explanation:

Hi there! The answer is x = -1
Let's solve this equation step by step!

First collect terms.

Subtract (1/2)x from both sides.

Subtract 3 from both sides.

And finally divide by -1 3/4
First multiply everything inside the brackets by seven
7x^4-42+3
Then solve what you can
7x^4-39
You an't solve it further. Is this what you mean? X to the fourth power?
