the price for one pair of pants is $12
Step-by-step explanation:
The question is incomplete. The complete question is
A shopper purchased 8 t shirts and 5 pairs of pants for $220. The next day he purchased 5 t shirts and 1 pair of pants for $112. How much does a t shirt and each pair of pants cost.
The solution is
Let x represent the price for one t shirt.
Let y represent the price for one pair of pants.
A shopper purchased 8 t shirts and 5 pairs of pants for $220. This means that
8x + 5y = 220 - - - - - - - - - -1
The next day he purchased 5 t shirts and 1 pair of pants for $112. This means that
5x + y = 112 - - - - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 8, it becomes
40x + 25y = 1100
40x + 8y = 896
Subtracting, it becomes
17y = 204
y = 204/ 17 = 12
Substituting y = 12 into equation 2, it becomes
5x + 12 = 112
5x = 112 - 12 = 100
x = 100/5 = 20

Step-by-step explanation:
When f(x) = f(x - 4), 3x² = 3(x - 4)².
=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.
The x-value is 2.
