Answer:
x=1
Step-by-step explanation:
Answer:
x=1 , y = -1
Step-by-step explanation:
-2.4x-3.6y = 1.2
2.4x+1.2y = 1.2
Add the equations together
-2.4x-3.6y = 1.2
2.4x+1.2y = 1.2
---------------------------
-2.4 y = 2.4
Divide by -2.4
y = -1
Now find x
2.4x +1.2y = 1.2
2.4x +1.2(-1) = 1.2
2.4x -1.2 = 1.2
Add 1.2 to each side
2.4x -1.2+1.2 = 1.2+1.2
2.4x = 2.4
Divide by 2.4
x = 1

Find the "unit cost." Divide the total price paid by the number of units sold:
$p
------------ = $(p/8) / lamp
8 lamps
The unit cost is p/8 dollars per lamp.
Cost of 1 shirt = s
cost of 1 pair of pants = 2s
1 shirt and 1 pants cost $18
s + 2s = 18
3s = 18
s = $6
