sovle 9m+9<3(5m-9)?

Answer 1

9m + 9 < 3(5m - 9)

First thing you can do is divide both sides by 3. Note that we can do this because the left hand side has two constants divisible by 3.

3m + 3 < 5m - 9

Now, put all terms with m in them on the left hand side, and everything else on the right hand side.

3m - 5m < -3 - 9

Simplify both sides

-2m < -12

Now, divide both sides by -2. Note that when doing so, the inequality sign switches (since we're dividing by a negative number).

m > 6

Answer 2

Did you mean 9m+9 = 3(5m-9) ??

9m + 9 = 3(5m-9)

First multiple the 3 through the numbers in the parenthesis.


9m + 9 = 15m - 27
Then move the m's so they're all on one side of the = sign.
Subtract 15m from each side of the = sign.

-6m + 9 = -27

Then subtract 9 from each side of the = sign.

-6m = -36

Then divide by -6 on each side of the = sign.

m = 6.

Remember whatever you do one one side of the = side has to be done to the other side too.
