equation #1:
x - y = 47
equation #2: deals with the number of legs
4x + 2y = 938, or
2x + y = 469
add our two equations:
3x = 516
take over....
Can you PLEASE help me with this Algebra problem:
In a hotel conference room, the number of chairs is 47 more than the number of people currently in the room. The total number of legs currently in this room is 938. What is the sum of the digits in the number of people currently in this room? Write a system of equations for this situation and find its solution.
This is what I have so far:
x = # of chairs
Y = # of people
number of legs = 938
I am not sure how to format the equation...but should I divide 938/2 = 469 number of people?
