Question

What is the solution to the equation 3.6m − 2.7 = −1.8m?

A. m = 0.25
B. m = 0.5
C. m = 1.25
D. m = 1.5

Answer 1

The value of m is 0.5

Option B is correct

Explanation:

Given equation

3.6m-2.7=-1.8m

On solving

Firstly we move the 1.8 m to left hand side in the equation

3.6m+1.8m=2.7

Now, On adding in left hand side

5.4m=2.7

On dividing of 2.7 by 5.4

`m=(2.7)/(5.4)`

`m = 0.5`

Hence, The value of m is 0.5

Answer 2

Option B is correct

m = 0.5 is the solution to the equation

Explanation:

Given the equation:

`3.6m-2.7= -1.8m`

Add 2.7 to both sides, we have;

`3.6m-2.7+2.7= -1.8m+2.7`

Simplify:

`3.6m = -1.8m+2.7`

Add 1.8 m to both sides we have;

`5.4m =2.7`

Divide both sides by 5.4 we have;

`m = (1)/(2) = 0.5`

⇒m = 0.5

Therefore, the solution for the given equation is, 0.5
