Question

Select the best possible first step to solving the following system by first eliminating the y variable.

4x + 5y = –8
3x + 2y = 1

Multiply the first equation by 2 and multiply the second equation by 5.
Multiply the first equation by –2 and multiply the second equation by –5.
Multiply the first equation by –2 and multiply the second equation by 5.
Multiply the first equation by 8 and the second equation by –8.

Answer 1

there are no BEST steps

Answer 2

there are only the steps that help you to solve

Answer 3

but it wants you to eliminate a y first

Answer 4

the step that will prolly get the quickest results; is number 3

Answer 5

but any of these will modify the equations into another form that may or maynot make life easier to the person solving it

Answer 6

that "best" complicates the answer and prosrcibes a method over math
