Answer:

x = 4.5

Step-by-step explanation:


\rightarrow \sf √(2x) + √(2x) = 6

add following


\rightarrow \sf 2√(2x) = 6

divide both sides by 2


\rightarrow \sf √(2x) = 3

square both sides


\rightarrow \sf 2x = 3^2

simplify the following


\rightarrow \sf 2x = 9

divide both sides by 2


\rightarrow \sf x = 4.5

Answer:

x = 9/2

Step-by-step explanation:

√2x + √2x = 6

2√2x = 6

2√2x/2 = 6/2

√2x = 3

(√2x)² =( 3)²

2x = 9

x = 9/2
