Solve 12−5x−4kx=y for x. show all your work!

12 - 5x - 4kx = y  

-5x -4kx = y - 12  

(-5 - 4k)x = y - 12  

x = (y - 12) /(-5 - 4k)  

x = (12 - y) / (4k + 5)

12−5x−4kx=y

Step 1: Add -12 to both sides.

−4kx−5x+12+−12=y+−12

−4kx−5x=y−12

Step 2: Factor out variable x.

x(−4k−5)=y−12

Step 3: Divide both sides by -4k-5.

x(−4k−5)−4k−5=y−12−4k−5

x=−y+124k+5

x=−y+124k+5

the answer is true.
