Question

2x + 7y = 15, 10x +py =45
​

Answer 1

Answer:

I DON'T KNOW IT DUDE HARD QUESTION

Answer 2

Step-by-step explanation:

• In this it is seems to ask. For what value of P such that there are no solution and unique solution.

• Here given data

        2 x +7 y  = 15       ...1)

        10 x +P y   = 45      ...2)

• For no solution required condition are

        $\mathbf{\frac{a_{1}}{a_{2}}=\frac{b_{1}}{b_{2}}\neq \frac{c_{1}}{c_{2}}}$

        On putting respective value

         $\mathbf{\frac{2}{10}=\frac{7}{P}\neq \frac{15}{45}}$

         For value of P first two term are required

         $\mathbf{\frac{2}{10}=\frac{7}{P}}$

         On solving

         P =35   This is for no solution required condition

• For unique solution required condition are

         $\mathbf{\frac{a_{1}}{a_{2}}\neq\frac{b_{1}}{b_{2}}}$

         $\mathbf{\frac{2}{10}\neq\frac{7}{P}}$

         $P\neq 35$   This is for unique solution required condition
