Solve for u 5u-u+3u=14

$5 u - u + 3 u = 14$

Step 1

Simplify $5 u - u + 3 u$ .

Subtract $u$ from $5 u$ .

$4 u + 3 u = 14$

Add $4 u$ and $3 u$ .

$7 u = 14$

Step 2

Divide each term in $7 u = 14$ by $7$ and simplify.

Divide each term in $7 u = 14$ by $7$ .

$\frac{7 u}{7} = \frac{14}{7}$

Simplify the left side.

Cancel the common factor of $7$ .

Cancel the common factor.

$\frac{7 u}{7} = \frac{14}{7}$

Divide $u$ by $1$ .

$u = \frac{14}{7}$

Simplify the right side.

Divide $14$ by $7$ .

$u = 2$
