Three days

During the three days sold in stationery 1490 workbooks. The first day sold about workbooks more than third day. The second day 190 workbooks sold less than third day. How many workbooks sold during each day?

Correct answer:

x =  600
y =  350
z =  540

Step-by-step explanation:


x+y+z=1490
x = 60+z
y = z-190

x+y+z = 1490
x-z = 60
y-z = -190

x = 600
y = 350
z = 540
