<PRE><B>Question 249146</B>
x = number of beggars
y = money you have.


your formulas are:


y - 7x = 24 (equation 1)
y - 9x = -32 (equation 2)


subtract equation 1 from equation 2 to get:


2x = 56


solve for x to get:


x = 28


substitute in first equation to get:


y - 7*28 = 24


solve for y to get:


y = 7*28 + 24 = 220


you have $220 dollars and there are 28 beggars at your door.


220 - 7*28 = 24 (true)
220 = 9*28 = -32 (true)
