Explanation:
To find the solution to the system of equations represented by the data in the table, we need to first write out the equations. Let's call the number of imports in a given month "x" and the number of exports "y". Then we have:
For January: 2x + 3y = total trade
For February: 4x + 4y = total trade
For March: 6x + 5y = total trade
For April: 8x + 6y = total trade
