The cost of one chapstick is $1 and one eyeliner is $2.
Step-by-step explanation:
Let,
Cost of one chapstick = x
Cost of one eyeliner = y
According to given statement;
3x+2y=7 Eqn 1
4x+5y=14 Eqn 2
Multiplying Eqn 1 by 4
Multiplying Eqn 2 by 3
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 7
Putting y=2 in Eqn 1
Dividing both sides by 3
The cost of one chapstick is $1 and one eyeliner is $2.
