How would you find M?

Question

4n/ab - c/m = x

thanks in advance for any help

Answer 1

the goal is to isolate m, so we have to get it by itself.

1. add c/m to both sides
2. subtract x from both sides
3. multiply both sides by m
4. divide both sides by everything but m
5. dividing by a fraction = multiply by reciprical

1. 4n/ab = c/m + x
2. 4n/ab - x = c/m
3. m*(4n/ab) = c
4. m = c/(4n/ab)
5. m = c * ab/4n

Answer 2

The usual way. Just follow the rules for pushing variables around an equals sign:
subtract 4n/ab from both sides.
multiply by -1 (all terms)
multiply both sides by m
factor out like terms for the coeffient of m
divide c by that coefficient to get the answer

Answer 3

Start by adding c/m to, and subtracting x from, both sides of the equation. It now reads 4n/ab - x = c/m. Now multiply the x term by ab/ab and put everything over ab on the left side to give you (4n-abx)/ab = c/m. Next, invert both sides to get m on top, and you get ab/(4n-abx) = m/c. Finally, multiply both sides by c to isolate m, and you end up with abc/(4n-abx) = m.

I notice that one of the other answerers made the x disappear.

Answer 4

Just rearrange the formula according to the normal rules of simple algebra in steps like this

4n/ab-x=c/m
and so on
