Answer: k=8

Explanation:

Let's multiply all by common denominator (x-5)(x+2) to get rid of fractions

3(x+2) - k(x-5) = 46 - 5x

3x+6-kx+5k = 46-5x

3x - kx + 6 +5k =46 -5x In order to balance an equation you can set constants equal to each other and x terms equal to each other so:

3x-kx= -5x or 6+5k=46

3-k=-5 5k=40

-k=-8 k=8

k=8
