Starting with
$2.2 x - \frac{6}{4} = - 7$ $2.2x - 6/4 = -7$

Multiply both sides by $4$ $4$ to get rid to the fraction
$8.8 x - 6 = - 28$ $8.8x - 6 = -28$

Add $6$ $6$ to both sides
$8.8 x = - 22$ $8.8x = -22$

Divide both sides by $8.8$ $8.8$
$x = - \frac{22}{8.8} = - 2.5$ $x = - (22)/(8.8) = -2.5$

The answer is: $x = - \frac{5}{2}$ $x=-5/2$ .

$\frac{22}{10} x = - 7 + \frac{3}{2} \Rightarrow \frac{11}{5} x = \frac{- 14 + 3}{2} \Rightarrow$ $22/10x=-7+3/2rArr11/5x=(-14+3)/2rArr$

$x = \frac{5}{11} \cdot (- \frac{11}{2}) \Rightarrow x = - \frac{5}{2}$ $x=5/11*(-11/2)rArrx=-5/2$ .
