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
