Respuesta :
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
Answer:
x=−y+124k+5
