Solve for n 8n+7=31

$8 n + 7 = 31$

Step 1

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

Subtract $7$ from both sides of the equation.

$8 n = 31 - 7$

Subtract $7$ from $31$ .

$8 n = 24$

Step 2

Divide each term in $8 n = 24$ by $8$ and simplify.

Divide each term in $8 n = 24$ by $8$ .

$\frac{8 n}{8} = \frac{24}{8}$

Simplify the left side.

Cancel the common factor of $8$ .

Cancel the common factor.

$\frac{8 n}{8} = \frac{24}{8}$

Divide $n$ by $1$ .

$n = \frac{24}{8}$

Simplify the right side.

Divide $24$ by $8$ .

$n = 3$
