Question

2x – 9y = 6
4x – 3y = –7
Which of the following would be the best first step to solve the system of equations?

Answer 1

"which of the following" implies that there are choices to pick from. WHERE ARE THE DAMNED CHOICES?

Answer 2

WHAT NIN SAID

Answer 3

A.
Multiply the first equation by 2.
B.
Multiply the second equation by 2.
C.
Multiply the first equation by –3.
D.
Multiply the second equation by –3.

Answer 4

lol oops.

Answer 5

D

Answer 6

thanks

Answer 7

That way you can cross out the y and solve for x.

Answer 8

Eliminate one of the variables, in any of the equations to substitute into the otther.
For example eliminate y in the first equation, and whatever y equals to, substitute that for y in the second equation. Understand?

Answer 9

Didn't see the choices.

Answer 10

For which system of equations is (5, 3) the solution?

A.
3x – 2y = 9
3x + 2y = 14
B.
x – y = –2
4x – 3y = 11
C.
–2x – y = –13
x + 2y = –11
D.
2x – y = 7
2x + 7y = 31
