Question

Find the value of K if the equation is inconsistent 4x+3y=11,8x+ky=7

Answer 1

The given system is
$4x + 3y = 11$
$8x + ky = 7$
Gn that the system is inconsistent
therefore
$\frac{4}{8} = \frac{3}{k} \: is \: not \: equal = \frac{11}{7}$
I and II ratios 》
$\frac{1}{2} = \frac{3}{k}$
Thus k = 6
