To solve the system of equations:

we can use either the substitution method or the elimination method. Here, I'll use the elimination method.First, let's eliminate

by making the coefficients of

in both equations equal. We can do this by multiplying the first equation by 3:1. Multiply the first equation by 3:

which simplifies to:

Now we have the system:

2. Add the two equations together to eliminate

This simplifies to:

3. Solve for

4. Substitute

back into the first equation to solve for

Simplify:

Thus, the solution to the system of equations is:
