Question

find h so that k =3 is a solution of the equation kx +8 =x-7

Answer 1

3x+8=x-7
3x-x=-7-8
2x=-15
x=-7.5

Answer 2

Hlo friend.. Cutiepie Here...

Here is ur answer :

K = 3

Kx + 8 = x - 7

Putting the value of k

$3x + 8 = x - 7$


$3x - x = - 7 - 8$


$2x = - 15$


$x = \frac{ - 15}{2}$


$x = - 7.5$
