-1= 1/(-2(1)+c)

- 1 = \frac{1}{- 2 ( 1 ) + c}

c = 1

Solution steps

- 1 = \frac{1}{- 2 ( 1 ) + c}

Simplify

\frac{1}{- 2 ( 1 ) + c} : \frac{1}{- 2 + c}

- 1 = \frac{1}{- 2 + c}

Multiply both sides by

- 2 + c

- (- 2 + c) = 1

Divide both sides by

- 1

- 2 + c = - 1

Move

2

to the right side

c = 1
