Evaluate

c - 7 c

Collect like terms by calculating the sum or difference of their coefficients

(1 - 7) c

Subtract the numbers

- 6 c

- 6 c - 8

Solution

- 2 (3 c + 4)

Show Solution

c = - \frac{4}{3}

Alternative Form

c = - 1. \dot{3}

Evaluate

c - 7 c - 8

To find the roots of the expression,set the expression equal to 0

c - 7 c - 8 = 0

Subtract the terms

More Steps

Simplify

c - 7 c

Collect like terms by calculating the sum or difference of their coefficients

(1 - 7) c

Subtract the numbers

- 6 c

- 6 c - 8 = 0

Move the constant to the right-hand side and change its sign

- 6 c = 0 + 8

Removing 0 doesn't change the value,so remove it from the expression

- 6 c = 8

Change the signs on both sides of the equation

6 c = - 8

Divide both sides

\frac{6 c}{6} = \frac{- 8}{6}

Divide the numbers

c = \frac{- 8}{6}

Solution

More Steps

Evaluate

\frac{- 8}{6}

Cancel out the common factor 2

\frac{- 4}{3}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

- \frac{4}{3}

c = - \frac{4}{3}

Alternative Form

c = - 1. \dot{3}
