A system of equations is shown below:


Equation A: 3c = d − 8

Equation B: c = 4d + 8


Which of the following steps should be performed to eliminate variable d first?


Multiply equation A by −4.

Multiply equation B by 3.

Multiply equation A by 3.

Multiply equation B by 4.

Verified Answer :

probably the first one "multiply equation A by -4". In order to cancel them out out multiply the first equation by negative 4 and then you add both equations once you add both equations -4+4=0 so they cancel out.
