Question

Find value of K if (2K-1,K) is solution of equation 10x-9y=12

Answer 1

10*(2k-1)-9*k=12
20k-10-9k=12
11k-10=12
11k=22
k=22/11=2
hope this will help you

Answer 2

Hey friend✋! here is your answer.

______________________________

✅To find - k

✅Given equation- 10x-9y=12

✔️ We know that (2k-1,k) first one is x coordinate & second is y coordinate

✅So put value of x & y in given equation

◆x=2k-1. & y=k

✔️10(2k-1)-9(k)=12

✅20k-10-9k=12

✔️11k=12+10

✔️11k=22

✅k=22/11

✅K=2

⭕️So the value of k is 2
