Question

What is the value of k in the equation (k - 1)/ 15 = 15/9 ?

Answer 1

Explanation:

everything can be found in the picture

Answer 2

`\\ \sf\longmapsto (k-1)/(15)=(15)/(9)`

`\\ \sf\longmapsto 9(k-1)=15^2`

`\\ \sf\longmapsto 9k-9=225`

`\\ \sf\longmapsto 9k=225+9`

`\\ \sf\longmapsto 9k=234`

`\\ \sf\longmapsto k=(234)/(9)`

`\\ \sf\longmapsto k=26`
