Start with the distributive property on both sides.
So It would become: 2-2x=3+6x+5
Add like terms: 2-2x=8+6x
Add two to both sides since its negative: 2=8+8x
Now subtract 8 from both sides: -6=8x
Now divide 8 on both sides: -6/8=8x/8
Since 8x/8 cancels out to 1x, it can be written as x
Simplify: -3/4
