-3(m-2n)=5m Solve for m

Question

I need help with this equation. Please list the steps to solve it.

Answer 1

The equation is:

 

-3 (m-2n) = 5m

 

First step is to distribute the -3 inside the parenthases:

 

-3m - (-3)2n = 5m

      ^^^^

      the two negative signs will cancel, to make this term  be 3*2n = 6n

 

So the equation becomes:

 

-3m + 6n = 5m

 

Bring the -3m over to the other side:

 

6n = 5m + 3m = 8m

 

Divide both sides by 2:

6/2*n = 8/2*m

 

And the simplified equation becomes:

 

3n = 4m

   

Answer 2

Distribute on left: -3m + 6n =5m

 

get m on same side: 6n = 8m

 

divide by 8 and simplify the fraction:  m=3/4 n
