Question 939493
Multiply thru by 10 to rid the decimals...:)
3x - 2 (3-5x) = -5 (x-6)
I'm 'old fashion( 2negatives = plus) 
3x- 6 + 10x = -5x + 30
18x = 36
x = 36/18 = 2
And...checking
3x - 2 (3-5x) = -5 (x-6)
6 -2(-7) = 6+ 14 = 20
....
-5 is the same as +(-5)
However: sooner or later will deal with 2 negatives = positive
