Question

If x=2k-1 and y=k is a solution of equation x-2y=4. Find the value of k

Answer 1

HEY MATE!
HERE IS YOUR SOLUTION....

Given, x=2k-1
and , y=k
therefore,
x-2y =4
→2k-1-2×k=4
→2k-1-2k=4
→0=5

hence here 2k and -2k cancelled which seems that your question is incorrect.....

Answer 2

$(2k - 1) - 2(k) = 4$
$2k - 1 - 2k = 4$
$2k - 2k = 4 + 1$
$2k + 2k = - 5$
$4k = - 5$
$k = - 5 \div 4$
