Question

Given the system of equations presented here: 3x + 5y = 29 x + 4y = 16 Which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? (5 points) Select one: a. Multiply the second equation by −1 to get −x − 4y = −16 b. Multiply the second equation by −3 to get −3x − 12y = −48 c. Multiply the first equation by −1 to get −3x − 5y = −29 d. Multiply the first equation by −3 to get −9x − 15y = −87
And pls show work

Answer 1

It would be b. If you combine -3x-5y and 3x+5y, the x's cancel out. That would be the variable.
