Solve for n -3n-4n-17=25

$- 3 n - 4 n - 17 = 25$

Step 1

Subtract $4 n$ from $- 3 n$ .

$- 7 n - 17 = 25$

Step 2

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

Add $17$ to both sides of the equation.

$- 7 n = 25 + 17$

Add $25$ and $17$ .

$- 7 n = 42$

Step 3

Divide each term in $- 7 n = 42$ by $- 7$ and simplify.

Divide each term in $- 7 n = 42$ by $- 7$ .

$\frac{- 7 n}{- 7} = \frac{42}{- 7}$

Simplify the left side.

Cancel the common factor of $- 7$ .

Cancel the common factor.

$\frac{- 7 n}{- 7} = \frac{42}{- 7}$

Divide $n$ by $1$ .

$n = \frac{42}{- 7}$

Simplify the right side.

Divide $42$ by $- 7$ .

$n = - 6$
