Question

best possible first step to solving the system by first eliminating the x variable.
3x + 5y = 1
2x + 4y = -4

do not know what I am doing

Answer 1

choices are

Multiply the first equation by 2 and multiply the second equation by 3.

Multiply the first equation by -2 and multiply the second equation by 3.

Multiply the first equation by -2 and multiply the second equation by -3.

None of the above

Answer 2

the first three choices can be correct depending on what process you'll involve the equations with to eliminate.
say:
(3x +5y=1)*2
(2x + 4y =-4) *3
you can eliminate x by subtracting the 2 equations
or
(3x +5y=1)*-2
(2x + 4y =-4) *3
you can eliminate by adding both equations
or
(3x +5y=1)*-2
(2x + 4y =-4) *-3
you can eliminate by subtracting the two equations

Answer 3

thank you
