See a solution process below:

#### Explanation:

First, group and combine like terms on the left side of the equation:

Next subtract

Now, divide each side of the equation by

A lot of explanation is given as I wish you to fully understand the process.

Thar bar over the

#### Explanation:

The objective is to have just one

To explain the principle using fruit.

Suppose you have two boxes. One containing 12 apples and the other containing 10 apples. You them empty one box into the other. Putting them together (adding). Consequently, that one box now has 12apples + 10apples =22 apples

Ok! Suppose that instead of using the word apples we just use the its first letter. We than have

Using the above concept.

Given:

Re grouping gives

The brackets have no purpose other than to emphasize the grouping.

Now we put all the numbers on the right.

Subtract

Note that the shortcut is to move it to the other side and give it the sign of the revers process. On the left it is add so on the right it is subtract

Now we get the

divide both sides by

Note that the short cut is to move it to the other side and give it the sign of the reverse process. On the left it is multiply. On the right it is divide.

But

There is no indication in the question that we may give an imprecise answer. The decimal solution would be

so if you rounded this it would not be precise.

Precise answers would be:
