Q: What is the solution of n if -4(3n+2)=20?

A: -4(3n + 2) = 20; -12n - 8 = 20; -12n = 20 + 8; -12n = 28; n = -28/12; n = -7/3

-4(3n + 2) = 20;

-12n - 8 = 20;

-12n = 20 + 8;

-12n = 28;

n = -28/12;

n = -7/3

-12n - 8 = 20;

-12n = 20 + 8;

-12n = 28;

n = -28/12;

n = -7/3

if m-9/2=5/4 what is the solution of m? **Weegy:** m = 5/4 + 9/2; m = 5/4 + 18/4; m = 23/4; m = 5 3/4 (More)

m-9/2=5/4

4(m-9) = 10

4m-36 = 10

4m = 46

m =46/4 =11.5

4(m-9) = 10

4m-36 = 10

4m = 46

m =46/4 =11.5

SCM, I don't understand how you got this answer. There is no bracket around m-9.

What i think is its a Simple proportion question and m-9 is a single number like x .

The question to me is like x/y = a/b where x = m-9.

@deb i don't think it needs one , the question is clear to me.

If it looks otherwise to you , you can flag it of course

as you already have xD
