Question

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

Answer 1

Answer:

B

3x + 5y = 29

3x + 5y = 29−3x − 12y = −48

Step-by-step explanation:

3x + 5y = 29................1

−3x − 12y = −48

-3(x + 4y) = -48

x + 4y = -48/-3

x + 4y = 16.....................2

Answer 2

Answer:

B

3x + 5y = 29

-3x - 12y = -48
