Explanation:
In order to write an equivalent equation for the first equation, you can multiply both sides by 15:

Then, you get this system of equations:

Now, you can apply the Elimination Method to solve the system of equations:
1. Multiply the second equation byb -3.
2. Add the equations.
3. Solve for "y".
Then:

4. Substitute the value of "y" into any original equation and solve for "x" in order to find its value:

5. The solution is:
