$$7 ( - x + 2 ) - 6 x = 5 ( - x - 1 ) - 3 x$$
$x = \frac{19}{5} = 3\frac{4}{5} = 3.8$
$$7\left(-x\right)+14-6x=5\left(-x-1\right)-3x$$
$$7\left(-x\right)+14-6x=5\left(-x\right)-5-3x$$
$$7\left(-x\right)+14-6x-5\left(-x\right)=-5-3x$$
$$2\left(-x\right)+14-6x=-5-3x$$
$$2\left(-x\right)+14-6x+3x=-5$$
$$2\left(-x\right)+14-3x=-5$$
$$2\left(-x\right)-3x=-5-14$$
$$2\left(-x\right)-3x=-19$$
$$-2x-3x=-19$$
$$-5x=-19$$
$$x=\frac{-19}{-5}$$
$$x=\frac{19}{5}$$
