Question

Q6. Find k so that x= -2 is the solution of kx+8=x-7​

Answer 1

Given:

kx + 8 = x - 7

Value:

x = -2

Explanation:

By putting the value of x, we get

k(-2) + 8 = (-2) - 7

or, -2k + 8 = -9

or, -2k = -9 - 8 = -17

or, k = -17/-2 = 17/2

Answer:

The value of k is 17/2 .

Answer 2

Answer:

Given:

kx + 8 = x - 7

Value:

x = -2

Explanation:

By putting the value of x, we get

k(-2) + 8 = (-2) - 7

or, -2k + 8 = -9

or, -2k = -9 - 8 = -17

or, k = -17/-2 = 17/2

Answer:

The value of k is 17/2 .
