Question

if x= 2k-2andy=k+1 is a solution of the equation 2x-y=4,then find the value of k
​

Answer 1

Step-by-step explanation:

2(2k-2)-k-1=4

4k-4-k-1=4

3k=4+5

3k=9

k=9/3

k=3

Answer 2

STEP BY STEP EXPLANATION

We have,

$x = 2k - 2 \\ y = k + 1 \\ 2x - y = 4 \\ 2(2k - 2) - (k + 1) = 4 \\ 4k - 4 - k - 1 = 4 \\ 3k - 5 = 4 \\ 3k = 4 + 5 = 9 \\ k = \frac{9}{3} = 3 \\ k = 3$

Hence, k=3 is the required solution
