2square root of x minus 5 = 2 solve for x

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
