##### 3 Answers

#### Answer:

#### Explanation:

Starting with the first equation, we need to make either x or y the subject (I chose x)

Now we simply substitute

Finally, we should also verify both answers by substituting both of them into the other equation again.

#3(3) + 5(-2) = -1

#### Answer:

See a solution process below:

#### Explanation:

**Step 1)** First, solve each equation for

**Equation 1:**
