Solve -9(n+7)=30

$$- 9 ( n + 7 ) = 30$$

Solve for n

$$n = -\frac{31}{3} = -10\frac{1}{3} \approx -10.333333333$$

Steps for Solving Linear Equation

Divide both sides by -9.

$$n+7=\frac{30}{-9}$$

Reduce the fraction \frac{30}{-9} to lowest terms by extracting and canceling out 3.

$$n+7=-\frac{10}{3}$$

Subtract 7 from both sides.

$$n=-\frac{10}{3}-7$$

Convert 7 to fraction \frac{21}{3}.

$$n=-\frac{10}{3}-\frac{21}{3}$$

Since -\frac{10}{3} and \frac{21}{3} have the same denominator, subtract them by subtracting their numerators.

$$n=\frac{-10-21}{3}$$

Subtract 21 from -10 to get -31.

$$n=-\frac{31}{3}$$
