You could give all of the fractions a common denominator. You could also solve each of them (1/2=0.5) to see their value and order them through the value.
The first thing you do is subtract 2 from both sides to move the 2 to the left side
3-6x=7x
now add 6x to both sides to move -6x to the right
3=13x
divide by 13 to eliminate the 13 on the right side
3/13
I don't know sorry I tried to work it but didn't work
