9/2m - 8 = - 5.5 + 4m

in a way like this

9 + 5k = 45 + 2k

operation

s 9 5k = 36 + 2k

s 2k 3 = 36

d 3 k = 12

**Ms. Sue**, Thursday, March 4, 2010 at 6:38pmIs this what you need?

9/2m - 8 = - 5.5 + 4m

9/2m = -5.5 + 8 + 4m

9/2m - 4m = 2.5

4 1/2m - 4m = 2.5

1/2m = 2.5

m = 2.5 / (1/2)

m = 2.5 / 0.5

m = 5

To check this answer, substitute 5 for m in the original problem.

**Casey**, Thursday, March 4, 2010 at 6:41pmWhat I'd advise is to balance the equation. What you do on one side of the equal sign, do it on the other.

9/2m-8= -5.5 + 4m

9/2m = 4 1/2m

4 1/2m -8= -5.5 + 4m

Add 8 on both sides

4 1/2m = 2.5 + 4m

Subtract 4m on both sides

1/2m = 2.5

Multiply 2 on both sides

m=5
