## anonymous one year ago 0.8m − 4 = −0.8m

1. anonymous

What is the solution to this equation?

2. rishavraj

-4 = - 0.8m - 0.8m

3. anonymous

m = 0.4?

4. rishavraj

hmmmmm -4 = -1.6m m = 4/1.6 m = 2.5

5. anonymous

How did -4 =-1.6m? I dont get it.

6. anonymous

Ooooh 0.8 + 0.8 right?

$0.8 m - 4 = -0.8 m$ $0.8 m - 0.8 m -4 = -0.8 m - 0.8 m$ $-4 = -1.6 m$ $4 = 1.6 m$ $m = \frac{ 4 }{ 1.6 }$
