Answer:

x=6/5 or 1.2

Step-by-step explanation:

I could not tell if your original problem was 2=-5x+8 or if it should have been 2x=-5x+8 so I solved both

2= -5x+8 (next subtract 8 from both sides)

-6= -5x (divide both sides by -5)

-6/-5=x (the negative cancel out next)

6/5 or 1.20 is x

If your original problem should say 2x=-5x+8

2x=-5x+8 (add 5x to both sides next)

7x=8 (divide by 7 on both sides)

x=8/7
