Solve -3=-7/8(-7)+c

$$- 3 = - 7 / 8 ( - 7 ) + c$$

Solve for c

$$c = -\frac{73}{8} = -9\frac{1}{8} = -9.125$$

Steps for Solving Linear Equation

Express -\frac{7}{8}\left(-7\right) as a single fraction.

$$-3=\frac{-7\left(-7\right)}{8}+c$$

Multiply -7 and -7 to get 49.

$$-3=\frac{49}{8}+c$$

Swap sides so that all variable terms are on the left hand side.

$$\frac{49}{8}+c=-3$$

Subtract \frac{49}{8} from both sides.

$$c=-3-\frac{49}{8}$$

Convert -3 to fraction -\frac{24}{8}.

$$c=-\frac{24}{8}-\frac{49}{8}$$

Since -\frac{24}{8} and \frac{49}{8} have the same denominator, subtract them by subtracting their numerators.

$$c=\frac{-24-49}{8}$$

Subtract 49 from -24 to get -73.

$$c=-\frac{73}{8}$$
