Solve -7(-3d-2/7)=72

$$- 7 ( - 3 d - \frac { 2 } { 7 } ) = 72$$

Solve for d

$$d = \frac{10}{3} = 3\frac{1}{3} \approx 3.333333333$$

Steps for Solving Linear Equation

Divide both sides by -7.

$$-3d-\frac{2}{7}=-\frac{72}{7}$$

Add \frac{2}{7} to both sides.

$$-3d=-\frac{72}{7}+\frac{2}{7}$$

Since -\frac{72}{7} and \frac{2}{7} have the same denominator, add them by adding their numerators.

$$-3d=\frac{-72+2}{7}$$

Add -72 and 2 to get -70.

$$-3d=\frac{-70}{7}$$

Divide -70 by 7 to get -10.

$$-3d=-10$$

Divide both sides by -3.

$$d=\frac{-10}{-3}$$

Fraction \frac{-10}{-3} can be simplified to \frac{10}{3} by removing the negative sign from both the numerator and the denominator.

$$d=\frac{10}{3}$$
