Question

Solve the system of equations.
6x – 3y = 3
–2x + 6y = 14
What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation?
What number would you multiply the first equation by in order to eliminate the y-terms when adding to the second equation?

Answer 1

Answer:

Step-by-step explanation:

Multiplying the second equation by 3 results in -6x + 18y = 42, which, when added to the first equation, has only y as a variable.  The x terms are eliminated.

Mult. the first equation by 2 results in 12x - 6y = 6, which, when added to the second equation, results in a third equation in which x is the only variable; the y terms are eliminated.

Answer 2

Answer:

multiply second by 3

multiply first by 2
