$$\frac{\left(- \frac{66}{5}\right) \frac{61 x}{10}}{\frac{17}{10}} = 3$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Divide both parts of the equation by -4026/85
We get the answer: x = -85/1342
((61/10)*x*-(66/5))/(17/10) = 3
Expand brackets in the left part
61/10x*-66/5)/17/10 = 3
Divide both parts of the equation by -4026/85
x = 3 / (-4026/85)
We get the answer: x = -85/1342
