PLEASE HELP I'LL MARK YOU BRAINLIEST Which system of equations is equivalent to the following system?

3x + 5y = 29
x + 4y = 16

A 3x + 5y = 29
−x − 4y = 16

B 3x + 5y = 29
−3x − 12y = −48

C −3x − 5y = 29
x + 4y = 16

D −9x − 15y = 87
x + 4y = 16

B

3x + 5y = 29

3x + 5y = 29−3x − 12y = −48

Step-by-step explanation:

3x + 5y = 291

−3x − 12y = −48

-3(x + 4y) = -48

x + 4y = -48/-3

x + 4y = 162

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
