You didn't say what you were supposed to do with that equation.

The answer to any "solving" problem may be checked by plugging it back into the original exercise:

. . . . .y = 3.2 - 0.2y

. . . . .[3] ?=? 3.2 - 0.2[3]

. . . . .3 ?=? 3.2 - 0.6

. . . . .3 ?=? 2.6

Since 3 does not equal 2.6, your solution is invalid. However, since you did not show your work, I'm afraid we cannot help you find your error.

If you wish to add to your original post, please reply with clarification, rather than re-editing your original post again.

Thank you.

Multiply your equation by 10:
10Y = 32 - 2Y : gets rid of decimal points; ain't that nice :wink:
Divide by 2:
5Y = 16 - Y : wow; how cute! Now can you finish that ?
