Solve for k.

16k − 15k = 14

k = 14

Step-by-step explanation:

You substract 16k - 15k which is 1k

Then divide both sides by 1

Your result is k=14

1 is b and 2 is d

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
