Final Answer: $Add to eliminate x$

Steps

Step 1 ：The system of equations is already set up in a way that makes it easy to eliminate x. If we add the two equations together, the x terms will cancel out, leaving us with an equation in terms of y. This seems like the correct first step.

Step 2 ：The equations are added together to eliminate x, resulting in a new equation in terms of y. The solution for y is -29/2. This confirms that the correct first step to solve the system of equations is to add the two equations together to eliminate x.

Step 3 ：Final Answer: $Add to eliminate x$
