Question

What is the solution to the equation 1.2m − 0.8 = −2.0m? m = 0.25 m = 0.4 m = 1 m = 4

Answer 1

The answer is m= 0.25

Answer 2

Option (a) is correct.

The solution of the equation 1.2m − 0.8 = −2.0m is 0.25

Explanation:

Given : Equation 1.2m − 0.8 = −2.0m

We have to find the solution for the given equation.

Consider the given equation 1.2m − 0.8 = −2.0m

Subtract 1.2m both side, we have,

− 0.8 = −2.0m -1.2m

Simplify, we have,

-0.8 = - 3.2m

Divide both side by -3.2 , we have,

`(-0.8)/(-3.2)=(-3.2m)/(-3.2)`

Simplify, we have,

m = 0.25

Thus, The solution of the equation 1.2m − 0.8 = −2.0m is 0.25
