Question

if x is equal to 2 k - 2 and Y = k + 1 is a solution of the equation 2 x -Y = 4 and then find the value of k​

Answer 1

Step-by-step explanation:

2k-2=0

k=1

y=k+1

y=2

so 2x-y=4

2x-1=4

2x=5

x=5/2

Answer 2

Step-by-step explanation:

given that 2k-2=x and y=k+1 is solution of 2x-y=4

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

4k-4-k-1=4

3k-5=4

3k=4+5

3k=9

k=3

therefore value of k is 3
