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?

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.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
