Question

Solve: 0.1m−1.3m=−2.1−2.7.

Answer 1

Answer: m=4

Explanation:

`0.1m-1.3m=-2.1-2.7`

add like terms

`-1.2m=-2.1-2.7`

subtract

`-2.1-2.7=-4.8`

`-1.2m=-4.8`

multiply both sides by 10

`-12m=-48`

divide -12 on both sides

m=4

Answer 2

Answer:4

Explanation:

Simplify what you can which is 0.1m-1.3m

you end up getting -1.2m

Now do the other side of the equation which is 2.1-2.7 which is -4.8

Divide -4.8 by -1.2 to get m=4
