$x = 2.8$ $x = 2.8$

Explanation:

Note that

$2.3 (x + 1.4) = - 9.66$ $2.3 ( x + 1.4) = -9.66$
$\Rightarrow x + 1.4 = \frac{- 9.66}{2.3}$ $implies x + 1.4 = (-9.66)/(2.3)$
$\Rightarrow x + 1.4 = 4.2$ $implies x + 1.4 = 4.2$
$\Rightarrow x = 4.2 - 1.4$ $implies x = 4.2 -1.4$
$\Rightarrow x = 2.8$ $implies x = 2.8$
