Answer 1

`\text{Solution:}\\\\\text{For first platter,}\\\text{Total cost}=2x+3y\\\text{or, }34=2x+3y....(1)\\\\\text{For second platter,}\\\text{Total cost}=3x+2y\\\text{or, }31=3x+2y.....(2)`

`\text{Multiplying equation (1) by 2 we get,}\\68=4x+6y....(3)\\\\\text{Multiplying equation (2) by 3 we get,}\\93=9x+6y.....(4)\\`

`\text{Subtracting equation (3) from equation (4),}\\93-68=9x-4x+6y-6y\\\text{or, }25=5x\\\text{or, }x=5\\\\\text{Equation (2) becomes}\\34=2(5)+3y\\\text{or, }3y=9\\\text{or, }y=3`

`\therefore\ \text{Each turkey sandwich costs 5 dollars. Each roast beef sandwich costs 3}\\\text{dollars.}`
