Sagot :
The price of fake teeth is $4 and the price of fake spiders is $1.50.
Two equations can be derived from this question:
5x + 10y = 35 equation 1
x = 4y - 2 equation 2
Where:
x = false teeth
y = fake spiders.
In order to determine the value of y, substitute for x in equation 1:
5(4y -2) + 10y = 35
20y - 10 + 10y = 35
Add similar terms
30y - 10 = 35
Combine similar terms
30y = 45
y = 45 / 30
y = $1.50
Substitute for y in equation 2
x = 4(1.50 - 2
x = 6 - 2
x = 4
