Let x and y be the cost of each pen and pencil, respectively. Based on the given above, two equations may be generated. These are,
(1) 3x + 5y = 15
( 2) 4x + 6y = 19
Solving for the values of x and y in these problems give x = 2.5 and y = 1.5. Thus, each pencil costs $1.5.
Answer:
-14y + 30
Step-by-step explanation:
Tell me if I am wrong but I think this is it.
Y(-2) = 3 (x - 4)
Y = 3 (-2 - 4)
Y = 6 + 12
Y= 18
