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
I think it's 35, because 49-14=35
Let's see..
? * ? = 28
Well, we know:
5 * 5 = 25
6 * 6 = 36
It must be closer to 5, yet much smaller than 6.
This formula solve by discriminant (D=b^2-4ac)
