Question

Find the value of k for which x= - 4, is a root of the equation x/2

+ x – 2 = kx – 1.​

Answer 1

Answer:

+x-2=kx -1

this is the answer

Answer 2

Answer:

$\frac{x}{2} + x - 2 = kx - 1 \\ \\ = > \frac{ - 4}{2} + ( - 4) - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 4}{2} + \frac{ - 4}{1} + ( - 4) - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 4 + ( - 8)}{2} + ( - 4) - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 12}{2} + ( - 4) - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 12}{2} + \frac{ - 4}{1} - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 12 + ( - 8)}{2} - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 20}{2} - 2 = k( - 4) - 1 \\ \\ = > \frac{ - 20}{2} - \frac{2}{1} = k( - 4) - 1 \\ \\ = > \frac{ - 20 - 4}{2} = k( - 4) - 1 \\ \\ = > \frac{ - 24}{2} = k( - 4) - 1 \\ \\ = > - 12 = k( - 4) - 1 \\ \\ = > - 12 = - 4k - 1 \\ \\ = > - 12 + 1 = - 4k \\ \\ - 11 = - 4k \\ \\ = > \frac{11}{4} = k$
