Question

For what value of a the following pair of linear equation has infinitely many solution ax-3y=1
-12x+ay=2

Answer 1

Answer: a = 6

step-by-step explanation:   a1=a, b1 = -3, c1 = -1

                                               a2 = -12, b2 = a = -2

In Infinitely many solutions, a1/a2 = b1/b2 = c1/c2

                                  Therefore, -a/12 = -3/a = 1/2

                                                     -a/12 = -3/a

                                                    $-a^{2}$ = -36

                                                       $a^{2}$ = 36

                                               Therefore a = 6
