Question

for what value of P will the following pair of linear equation have infinitely many solutions P - 3 x + 3 Y is equal to p p x + P Y is equal to 12​

Answer 1

Answer:

+6 or -6

Step-by-step explanation:

For infinitely many solutions of the pair of the linear equations

    $\frac{a1}{a2} =\frac{b1}{b2 } =\frac{c1}{c2}$

=> $\frac{p-3}{p} = \frac{3}{p} = \frac{-p}{-12}$

Taking \frac{3}{p} = \frac{-p}{-12}, we have

=> $\frac{3}{p} = \frac{p}{12}$

=>$p * p = 3 *12$

=> $p^{2} = 36$

=> $p = +6 or -6$

Answer 2

Answer:

+6 or -6

Step-by-step explanation:

For infinitely many solutions of the pair of the linear equations

    \frac{a1}{a2} =\frac{b1}{b2 } =\frac{c1}{c2}

=> \frac{p-3}{p} = \frac{3}{p} = \frac{-p}{-12}

Taking \frac{3}{p} = \frac{-p}{-12}, we have

=> \frac{3}{p} = \frac{p}{12}

=>p * p = 3 *12

=> p^{2} = 36

=> p = +6 or -6
