If the weight of hardcover version is double the weight of paperback version then weight of hardcover version is 2.8 pounds and the weight of paperback version is 1.4 pounds.
An equation is a relationship between variables in equal to form. It is evaluated to find the values of variables.
The weight of hardcover book is h
The weight of paperback version is p.
According to question:
h=2p (weight of hardcover version is double the weight of paperback version)
h+ p= 4.2 (weight of hardcover version and weight of paperback version is equal to 4.2 pounds)
Put the value of h=2p in h+ p=4.2
2p+p=4.2
3p=4.2
p=1.4
Put the value of p=1.4 in h=2p to get the value of h
h=2p
=2*1.4
=2.8
Hence the weight of hardcover version is 2.8 pounds and the weight of paperback version is 1.4 pounds.

Hey there!
5y + 2y + 6 + 2
COMBINE the LIKE TERMS
= (5y + 2y) + (6 + 2)
= 7y + 8
Overall answer: 7y + 8
The QUESTION ANSWER:
Distributive property:
5y + 2(y + 3) + 2
Combining the like terms:
6y - y + 2y + 10 - 4 + 2
Commutative property:
5y + 2 + 6 + 2y
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
FORMULAS: (for properties for addition)
COMBINING LIKE TERMS:
a + b + a + b
= 1a + 1b + 1a + 1b
= (1a + 1a) + (1b + 1b)
= 1a + 1a + 1b + 1b
= 2a + 2b
DISTRIBUTIVE PROPERTY:
a(b + c)
= a(b) + a(c)
= ab + ac
COMMUTATIVE PROPERTY:
a + b + c
= b + c + a
= c + b + a
