Subtract the second equation from the 1st equation
You need the following equation
![26 - 3.5x = 8.5 \\ - 3.5x = - 17.5 \\ x = 5](https://tex.z-dn.net/?f=26%20-%203.5x%20%3D%208.5%20%5C%5C%20%20-%203.5x%20%3D%20%20-%2017.5%20%5C%5C%20%20x%20%3D%205)
5 pens were purchased.
Answer:
(2y - 5) (3y^2 - 4)
Step-by-step explanation:
Group and factor by using the Greatest Common Factor (GCF).
6y^3 - 15y^2 - 8y + 20
Simply multiply the terms inside the first pair of parenthesis, by the terms in the second pair of parenthesis.
2y x 3y^2 = 6y^3
2y x (-4) = 8y
-5 x 3y^2 = 15y^2
-5 x (-4) = 20
6y^3 - 8y -15y^2 + 20
Now, simply simplify the problem!
(2y - 5) (3y^2 - 4)
