Answer 1

Answer:

k=10

Step-by-step explanation:

x=2x-1

y=k

3x-5y-7=0

3(2x-1)-5*k-7=0

6k-3-5k-7=0

6k-5k-3-7=0

k-10=0

k=0

Answer 2

Answer:

k=10

Step-by-step explanation:

given x=2k-1 , y=k

eq is 3x-5y-7

substituting x&y values in eq, we get

3(2k-1)-5(k)-7=0

6k-3-5k-7=0

k-10 =0

k=10

therefore k=10
