Question 1066863
x and y are the two amounts.
.05x+.08y=4650
.08x+.05y=5100
5x+8y=465000, multiplying by 100
8x+5y=510000
Multiply the top by -8 and the bottom by +5 to eliminate x
-40x-64y=-3720000
40x+25y=2550000
-39y=-1170000
y=P30000
5x+240000=465000
5x=225000
x=P45000
.05(45000)+.08(30000)=2250+2400=4650
.08(45000)+.05(30000)=3600+1500=5100
