2/3(x - 3) + 1/2x = -10
I worked out this much:
2/3x - 2 + 1/2x = -10
7/6x - 2 = -10
7/6x - 2+ 2 =-10 + 2
7/6x = -8
But I don't know what to do next. =\

----> 2/3x – 2 + 1/2x = –10
2/3x – 2 + 1/2x = –10
7/6x – 2 = –10
7/6x – 2 + 2 = – 10 + 2
7/6x = – 8
7×6x/ 6x = – 8 × 6 x
7 = – 48 x
x = – 7/48

2/3x - 2 + 1/2x = -10
2/3x + 1/2x = -8
4/6x + 3/6x = -8
7/6x = -8
7 = -48x
x = 7/-48

-8 divided by 7/6

Great job so far. Let's multiply each side by 6.
7x=-8
Then divide each side by 7:
x= -48/7 or -6.857
