What is the value of x in the equation below 6 (x - 8) equals 72

Here is the equation:

In the equation, 6 is being multiplied by x - 8. There are two ways to solve this equation.

FIRST METHOD

You need to remove the parentheses by multiplying everything in the parentheses by 6.

Multiply:

Remember:

NEGATIVES

POSITIVES

Now combine the two values and rewrite the equation:

Since you're looking for x alone, you will need to remove the -48. This can be done by adding 48 to both sides, -48+48=0, which cancels it out).

Lastly, divide both sides by 6 to leave x alone.

SECOND METHOD

While the first step is somewhat complicated, there is a much easier way.

Start by dividing both sides by 6 to remove the number next to the parentheses.

(The 6 is cancelled out since 6 divided by 6 equals 1, and 1 × any number is that number).

Now you need to leave the variable alone, which can be done by adding 8 to both sides(-8+8=0 and -8 is cancelled out).

Either method can be used, but the second one is definitely shorter!

The answer is x = 20.
