Answer:
x is 49/4, or 12 1/4 or 12.25
Step-by-step explanation:
To solve 2√x - 5 = 2, do the following:
Add 5 to both sides
2√x - 5 + 5 = 2 + 5
-5 and 5 cancel out.
2√x = 7
Divide both sides by 2 (This undoes the multiplication by 2 from the left side of this equation)
(2√x)/2 = 7/2
√x = 7/2
Square both sides of the equation
(√x)² = (7/2)²
x = 49/4
Convert as needed
x = 12 1/4 or 12.25
