Jan 30, 2016

$c = - \frac{51}{150} = - 0.34$

#### Explanation:

Collecting Like terms

$\left(0.5 - 2\right) c + 3.49 = 4$

$- 1.5 c + 3.49 = 4$

Subtract 3.49 from both sides

$- 1.5 c = 0.51$

Multiply both sides by 100

$- 150 c = 51$

Divide both sides by -150

$c = - \frac{51}{150} = - 0.34$
