Question

0.8m − 4 = −0.8m

Answer 1

What is the solution to this equation?

Answer 2

-4 = - 0.8m - 0.8m

Answer 3

m = 0.4?

Answer 4

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

Answer 5

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

Answer 6

Ooooh 0.8 + 0.8 right?

Answer 7

\[0.8 m - 4 = -0.8 m\]
\[0.8 m - 0.8 m -4 = -0.8 m - 0.8 m\]
\[-4 = -1.6 m\]
\[4 = 1.6 m\]
\[m = \frac{ 4 }{ 1.6 }\]
