Equations
What values of X and Y would make these equations work?
6751X + 3249Y = 26751
3249X + 6751Y = 23249
6751X + 3249Y = 26751
3249X + 6751Y = 23249
Answer
Add the equations to give: 10000X + 10000Y = 50000Divide by 10000 to give: X + Y = 5
Subtract to give: 3502X - 3502Y = 3502
Divide by 3502 to give: X - Y = 1
Therefore: X = 3 and Y = 2
