Solve for u 2(u-9)=4

$2 (u - 9) = 4$

Step 1

Divide each term in $2 (u - 9) = 4$ by $2$ and simplify.

Divide each term in $2 (u - 9) = 4$ by $2$ .

$\frac{2 (u - 9)}{2} = \frac{4}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 (u - 9)}{2} = \frac{4}{2}$

Divide $u - 9$ by $1$ .

$u - 9 = \frac{4}{2}$

Simplify the right side.

Divide $4$ by $2$ .

$u - 9 = 2$

Step 2

Move all terms not containing $u$ to the right side of the equation.

Add $9$ to both sides of the equation.

$u = 2 + 9$

Add $2$ and $9$ .

$u = 11$
