Answer:
skirts = 1
pants = 1
Step-by-step explanation:
Suppose the number of skirts Ritu has bought = x
Suppose the number of pants Ritu has bought = y
Given in the question that the number of skirt is seven less than eight times the number of pants purchased
so,
Equation 1
x = 8y - 7
The number of skirts is four less than five times the number of pants purchased
Equation 2
x = 5y - 4
Substitute for x from equation 1
8y - 7 = 5y - 4
8y - 5y = -4 + 7
3y = 3
y = 1
Plug value of y in equation 1
x = 8(1) - 7
x = 1
