Question

HellllPPPPP solve this equation: 0.2 - 2m = 2.1m + 2.5 - 1.8m

Answer 1

The answer is -1.........

Answer 2

Explanation:

First simplify it. Combine like terms.

0.2 - 2m = 2.1m + 2.5 - 1.8m

0.2 - 2m = 0.3m + 2.5

Then isolate m. Add 2m on both sides, then subtract 2.5 from both sides.

0.2 - 2m = 0.3m + 2.5

0.2 = 2.3m + 2.5

-2.3 = 2.3m

Now divide by 2.3 to find m.

-2.3 = 2.3m

-1 = m

And so m = -1.
