Question

Find the value of a the following system of linear equation has no solution ax+3y=a-2& 12x+ay=a​

Answer 1

Answer:

ax+3y=a-2;

12x+ay=a

Step-by-step explanation:

a₁/a₂=b₁/b₂≠c₁c₂ is Parallel line has no solution

$\frac{a}{12} = \frac{3}{a} \\ {a}^{2} = 3 \times 12 \\ {a}^{2} = 36 \\ a = \sqrt{36} \\ a = 6$

Answer. a=6
