Solve the Inequality for N -9+3(7N+1)<=2N-1+5N

$- 9 + 3 (7 N + 1) \leq 2 N - 1 + 5 N$

Rewrite so $N$ is on the left side of the inequality.

$2 N - 1 + 5 N \geq - 9 + 3 (7 N + 1)$

Add $2 N$ and $5 N$ .

$7 N - 1 \geq - 9 + 3 (7 N + 1)$

Simplify $- 9 + 3 (7 N + 1)$ .

Simplify each term.

Apply the distributive property.

$7 N - 1 \geq - 9 + 3 (7 N) + 3 \cdot 1$

Multiply $7$ by $3$ .

$7 N - 1 \geq - 9 + 21 N + 3 \cdot 1$

Multiply $3$ by $1$ .

$7 N - 1 \geq - 9 + 21 N + 3$

Add $- 9$ and $3$ .

$7 N - 1 \geq 21 N - 6$

Move all terms containing $N$ to the left side of the inequality.

Subtract $21 N$ from both sides of the inequality.

$7 N - 1 - 21 N \geq - 6$

Subtract $21 N$ from $7 N$ .

$- 14 N - 1 \geq - 6$

Move all terms not containing $N$ to the right side of the inequality.

Add $1$ to both sides of the inequality.

$- 14 N \geq - 6 + 1$

Add $- 6$ and $1$ .

$- 14 N \geq - 5$

Divide each term in $- 14 N \geq - 5$ by $- 14$ and simplify.

Divide each term in $- 14 N \geq - 5$ by $- 14$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- 14 N}{- 14} \leq \frac{- 5}{- 14}$

Simplify the left side.

Cancel the common factor of $- 14$ .

Cancel the common factor.

$\frac{- 14 N}{- 14} \leq \frac{- 5}{- 14}$

Divide $N$ by $1$ .

$N \leq \frac{- 5}{- 14}$

Simplify the right side.

Dividing two negative values results in a positive value.

$N \leq \frac{5}{14}$

The result can be shown in multiple forms.

Inequality Form:

$N \leq \frac{5}{14}$

Interval Notation:

$(- \infty, \frac{5}{14}]$
