Minus the 21 from the other side of the equation making it 7x=-21 then u divide the 7 from the x to the -21 resulting in x=-3

Answer:

x = 27

Step-by-step explanation:

Given

$\sqrt{2x+10}$ - 6 = 2 ( add 6 to both sides )

$\sqrt{2x+10}$ = 8 ( square both sides )

2x + 10 = 8² = 64 ( subtract 10 from both sides )

2x = 54 ( divide both sides by 2 )

x = 27
