I had this question
Answer:
The domain of a rational function consists of all the real numbers x except those for which the denominator is 0 . To find these x values to be excluded from the domain of a rational function, equate the denominator to zero and solve for x .

Which variable would you like to solve for?
Let's try solving for y since you have two of them.
ky - bf = fy/m
kym - bfm = fy --> [ multiply by m ]
kym - fy = bfm --> [ subtract fy on both sides ]
y(km-f) = bfm ---> [ factor out a y ]
y = bfm/(km-f) ---> [ divide by km-f on both sides ]
The correct answer is:
x + 2y = −10
<span>3x − y = 12

Just did this test, and got that question correct.
Hope this helps!
