Question

Solve: 0.1m−1.3m=−2.1−2.7.

Answer 1

Answer:4

Step-by-step 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

Answer 2

Answer: m=4

Step-by-step 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
