First of all, know how to multiply and divide integers.

Just like with adding and subtracting, the basic strategy of all this is to get x by itself without any negative sign in front. Remember that -x means (-1)x.

The other thing to remember is that **x is a number**. That means
you can multiply or divide it just like any other number.

**Example 1:** Solve

-2x = 8

This is pretty basic. We divide both sides by -2. The answer is

**Example 2:** Solve

x/3 = -6

This is not rocket science. Multiply both sides by 3. The answer is

**Example 3:** Solve

18/x = -6

What we have to do here is
cross-multiply the x and -6. The
answer is

Of course, there is no law that says the numbers in the problem have to be integers.

**Example 4:** Solve

0.18 = 0.12(600,000/x)

If we multiply both sides by 100 we get
