Question

If x= 2k - 1 and y = k is a solution of the equation 3x - 5 y - 7 = 0, find the value of k . Also find two​

Answer 1

Answer:

k=13 , x=25,y=13

Step-by-step explanation:

given x=2k-1 , y=k

substituting x and y in equation 3x-5y-7

3{2k-1} - 5 {k} - 7

6k-6 -5k-7 = 0

k-13 = 0

so, k= 13

x=2k-1 =25

y=k=13
