8 and 14/15
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
(-6) x (-3) = 18 (-10) x (-9) = 90 18 - 90 = -72
If you mean: 5 and 6/10 minus 6/10 then the answer is 5
-5 + (-4) - 12 - 20 - (-10) + 6 = -25
3 minus 3/18 is 2 5/6
five over nine is 10 over 18, five over six is 15 over 18, 10-15=-5 over -18 .....-5 18
5/2 - 6/5 = 25/10 - 12/10 = 13/10 or 1.3
8 x (6 - 5) / 10 = 0.8
6*34+10-5=209
7/18 minus 5/6 is -4/9
3/5 is 6/10. (6-3)/10 is 3/10
6 and 7/10 minus 3 and 3/5 = 31/10 or 3 and 1/10
