Step-by-step explanation:
book= y
pen = x
solution,
y + x = 63. y+5x=75
transposing method
(y-y) + (5x-x) = 75-63
4x = 12
x = 12/4
x = 3
Cost of 1 pen is 73
to find cost of book we will simply use
algebra
1 equation = 1 book + 1 pen = 63
y+x = 63
y+3 (x =3) = 63
y = 63-3
V=60
If you want to check you can also solve 2 equation
2 equation=1 book + 5 pen
= y + 5x
= y +(5-3) = 75
= y + 15 = 75
= y = 75-15
y = 60
