we use this value for

#### Explanation:

Given the following linear system, you may choose from either performing the substitution method or the elimination method. For this example I would show both and it would be up to you to choose which method you are more comfortable with. However note that using any of the two aforementioned method would produce the same result.

**Substitution Method:**

For this method, since the

Since we now have the value of

In the same way, when we use the Elimination Method, we would arrive at the same answer.

**Elimination Method**

Multiplying the first equation by 5

Adding the two equations to eliminate

Computing for

Hence the ordered pair/solution to this linear equation is:
