Solve for x 16x-15-9x=13

$16 x - 15 - 9 x = 13$

Step 1

Subtract $9 x$ from $16 x$ .

$7 x - 15 = 13$

Step 2

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

Add $15$ to both sides of the equation.

$7 x = 13 + 15$

Add $13$ and $15$ .

$7 x = 28$

Step 3

Divide each term in $7 x = 28$ by $7$ and simplify.

Divide each term in $7 x = 28$ by $7$ .

$\frac{7 x}{7} = \frac{28}{7}$

Simplify the left side.

Cancel the common factor of $7$ .

Cancel the common factor.

$\frac{7 x}{7} = \frac{28}{7}$

Divide $x$ by $1$ .

$x = \frac{28}{7}$

Simplify the right side.

Divide $28$ by $7$ .

$x = 4$
