Question

Find from u.

-12u = -24

Answer 1

If you would like to solve the equation -12 * u = - 24 for u, you can calculate this using the following step:

- 12 * u = - 24
12 * u = 24 /12
u = 24 / 12
u = 2

The correct result would be 2.

Answer 2

Well, to find u, we have to remove all that is attached to it so the equation can just be u=...
To find u, you have to remove what is attached to it, and that is -12. Then you have to look at the relationship between the -12 and u. The relationship is multiplication, and the opposite of multiplication is division, so all you have to do is divide both sides by -12. So;
-12u/-12=-24/-12
The -12 cancels the -12, leaving u and the - in 12 cancels the - in 24. Leaving 24/12. And that is 2. Written as;
u=2
