Answer:
![b) 5 (x-3)\\c) 4 x + 3 y-15- 3 y + x\\e) -20 - 3 x + 5 + 8 x](https://tex.z-dn.net/?f=b%29%205%20%28x-3%29%5C%5Cc%29%204%20x%20%2B%203%20y-15-%203%20y%20%2B%20x%5C%5Ce%29%20-20%20-%203%20x%20%2B%205%20%2B%208%20x)
Step-by-step explanation:
We are given the following expression in the question:
![5x-15](https://tex.z-dn.net/?f=5x-15)
a)
![5 (x + 15)\\=5(x) + 5(15)\\=5x + 75](https://tex.z-dn.net/?f=5%20%28x%20%2B%2015%29%5C%5C%3D5%28x%29%20%2B%205%2815%29%5C%5C%3D5x%20%2B%2075)
which is not equivalent to the given expression.
b)
![5 (x-3)\\=5(x)-3(5)\\=5x-15](https://tex.z-dn.net/?f=5%20%28x-3%29%5C%5C%3D5%28x%29-3%285%29%5C%5C%3D5x-15)
which is equivalent to the given expression
c)
![4 x + 3 y-15- 3 y + x\\=4x+x+3y-3y-15\\=5x-15\\=5(x-3)](https://tex.z-dn.net/?f=4%20x%20%2B%203%20y-15-%203%20y%20%2B%20x%5C%5C%3D4x%2Bx%2B3y-3y-15%5C%5C%3D5x-15%5C%5C%3D5%28x-3%29)
which is equivalent to the given expression.
d)
![-7 y-6 x- 8 y + x\\=-7y-8y-6x+x\\=-15y-5x\\=-5(x+3y)](https://tex.z-dn.net/?f=-7%20y-6%20x-%208%20y%20%2B%20x%5C%5C%3D-7y-8y-6x%2Bx%5C%5C%3D-15y-5x%5C%5C%3D-5%28x%2B3y%29)
which is not equivalent to the given expression.
e)
![-20 - 3 x + 5 + 8 x\\=-3x+8x-20+5\\=5x-15](https://tex.z-dn.net/?f=-20%20-%203%20x%20%2B%205%20%2B%208%20x%5C%5C%3D-3x%2B8x-20%2B5%5C%5C%3D5x-15)
which is equivalent to the given expression.
