Your question can be construeded in different ways so an exact is not possible.
But when dealing with equations involving fractions the first steps are to eliminate the fractions.

x - 2 + 5/7 = 2/3
x = 2/3 + 2 - 5/7 = (14 + 42 - 15)/21 = 41/21
x=-1 ^ how do you know?
(-1/6) - 2/3 = -0.8333333332
2/5 = 4/10 minus 1/10 is 3/10
2x+3y=13 3x-y=3 x=2
81
3/2 minus 2 equals -1/2
-2, 3
2 over 3 can not be simplified 2 over 3 minus 1 over 6 equals one-half
(t-7)/w = (-3-7)/-2 = -10/-2 = +5 ( minus over minus = plus)
It can do. Depends on the value of x.
6 and 11/14
y= 1/2x - 2/3
20 minus 17 minus 3 minus 2 equals -2
so, if 2 minus Ln times 3 minus x equals 0, then 2 minus Ln times 3 equals x, therefore 2 minus Ln equals x divided by three, so Ln + X/3 = 2 therefore, (Ln + [X/3]) = 1
x=3/2
3 - 2
-2
