Evaluate the Formula 2y = square root of x , x=4

$2 y = \sqrt{x}$ , $x = 4$

Step 1

Substitute $4$ in for $x$ .

$2 y = \sqrt{4}$

Step 2

Solve for $y$ .

Remove parentheses.

$2 y = \sqrt{4}$

Divide each term in $2 y = \sqrt{4}$ by $2$ and simplify.

Divide each term in $2 y = \sqrt{4}$ by $2$ .

$\frac{2 y}{2} = \frac{\sqrt{4}}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 y}{2} = \frac{\sqrt{4}}{2}$

Divide $y$ by $1$ .

$y = \frac{\sqrt{4}}{2}$

Simplify the right side.

Simplify the numerator.

Rewrite $4$ as $2^{2}$ .

$y = \frac{\sqrt{2^{2}}}{2}$

Pull terms out from under the radical, assuming positive real numbers.

$y = \frac{2}{2}$

Divide $2$ by $2$ .

$y = 1$
