Find other solutions in explanation
x = 250
y = 1750
Step-by-step explanation:
x = cost per copybook
y = cost per pen
2. Sum of the cost of 4 copy books and 3 pen is equal to 7750
3.)
2x+y=2750 - - (1)
4x + 3y = 7750 - - - (2)
From (1)
y = 2750 - 2x
Substitute y = 2750 - 2x into (2)
4x + 3(2750 - 2x) = 7750
4x + 8250 - 6x = 7750
-2x = - 500
x = 500/2
x = 250
y = 2750 - 2(500)
y = 2750 - 1000
y = 1750
