x = 2.92

#### Explanation:

to solve equations of this type you collect the terms with the variable in them to one side of the equation , usually the left hand side and the constants to the other side.

-2.5x + 2.8 = - 4.5 becomes

-2.5x = -4.5 - 2.8

$\Rightarrow - 2.5 x = - 7.3$ ( now divide both sides by - 2.5 )

$\Rightarrow \frac{- 2.5 x}{-} 2.5 = \frac{- 7.3}{-} 2.5$

$\Rightarrow x = 2.92$
