Question

if x=2k-1 and y =k is a solution of equation 3x-5y-7=0 ,find k

Answer 1

hii...
the solution is...
given:-x=2k-1 and y=k
substituting the values in the given equation
3(2k-1)-5(k)-7=0
6k-3-5k-7=0
k-10=0
k=10
therefore the value of k is 10.

Answer 2

putting the value of x and y in the given equation
3x-5y-7=0
3(2k-1)-5k-7=0
6k-3-5k-7=0
k-3-7=0
k=10
