I know this is really simple, but I can't seem to work this out without getting a weird answer.

The equation I have to solve is 8-5x = 2

Anyone care to help out?

8-5x = 2

+5x on both sides

8-5x+5x = 2+5x

8 = 2+5x

-2 on both sides

8-2 = 2+5x-2

8-2 = 2-2+5x

6 = 5x

divide both sides by 5

6/5 = 5x/5

6/5 = 1x

6/5 = x

x=6/5=1 1/5 = 1.2

[input]8-5x = 2[/input]

+5x on both sides

8-5x+5x = 2+5x

8 = 2+5x

-2 on both sides

8-2 = 2+5x-2

8-2 = 2-2+5x

6 = 5x

divide both sides by 5

6/5 = 5x/5

6/5 = 1x

6/5 = x

x=6/5=1 1/5 = 1.2

[input]8-5x = 2[/input]

THIS IS RIGHT. but it's written TOO complicated.

here's an easier way:

8-5x = 2

+5x on both sides

-> 8 = 2 + 5x

-2 on both sides

-> 6 = 5x

then, to find out what the x is, you have to get to leave the x alone, so you divide it by 5 on both sides.

-> x = 6/5 ( six divided by 5 )

-> x = 1.2

HOPE THAT I HELPED YOU.

SINCERELY ALICIA.
