<PRE><B>Question 875598</B>
2a + 3e =  58.75
4a + 5e = 102.50
solve first equation for a
2a = 58.75 - 3e
a = (58.75 - 3e) / 2
now substitute for a in the second equation
4(58.75 - 3e) / 2 +5e = 102.50
2(58.75 - 3e) + 5e = 102.50
117.50 - 6e + 5e = 102.50
-e = -15
e = 15.00
now substitute for e in first equation
2a + 45.00 = 58.75
2a = 13.75
a = 6.875
therefore
e = $15.00 and a = $6.875
