The problem says write the sum of solutions of 3√2-x = x-4 and I don't know how to write the sum of the solutions?

Question

Just really need to know how to write the answer using sum of solutions

 

Answer 1

3√2 - x = x - 4

 

Add x to both sides and get

 

3√2 = 2x - 4

 

Add 4 to both sides and get

 

3√2 + 4 = 2x

 

Divide both sides by 2 and get

 

x = 2 + (3/2)√2
