2k-1-5k+6=0. Find the value of k

Mathematics
1 answer:
Lorico [155]3 years ago
3 0

Answer:

k = 5/3

Step-by-step explanation:

Solve for k:

5 - 3 k = 0

Subtract 5 from both sides:

(5 - 5) - 3 k = -5

5 - 5 = 0:

-3 k = -5

Divide both sides of -3 k = -5 by -3:

(-3 k)/(-3) = (-5)/(-3)

(-3)/(-3) = 1:

k = (-5)/(-3)

Multiply numerator and denominator of (-5)/(-3) by -1:

Answer: k = 5/3

Black_prince [1.1K]

Black = 2*3 = 6 cars;

Blue = 2*2*3 = 12 cars;

Red = cars;

White = 2*9 = 18 cars;

The number of each colour car is a factor of 36( blue, red, white);

black + blue + red + white = 45 cars.
