Answer:

100 Rs 5 coins and 50 Rs 2 coins

Step-by-step explanation:

Bhairav collected Rs.600 in his piggy bank by putting in Rs.2 and Rs.5 coins. The number of Rs.5 coins are twice as many as Rs.2 coins

Let x be the number of 5 coins

and y be the number of 2 coins

The number of Rs.5 coins are twice as many as Rs.2 coins

x=2y

5x+2y=600

Replace x with 2y

5x+2y=600\\5(2y)+2y=600\\10y+2y=600\\12y=600\\y=50

x=2y\\x=2(50)\\x=100

So 100 Rs 5 coins and 50 Rs 2 coins

A system of linear equations is shown below.
yulyashka [42]

Answer: No solution

Step-by-step explanation:

2m+4p=22

6m+12p=66

First, to choose one variable to simplified, I choose to find 1st equations in m form.

2m+4p=22

      2m=22-4p            [Subtract 4p from both side]

         m=22/2 - 4/2p  [Divide 2 on both side to find m]

         m= 11 - 2p

6m+12p=66          

6(11-2p)+12p=66          [Plug in the 11-2p in to m,according to the 1st equation]

66-12p+12p=66

The -12p has cancel with 12p, so it means that there is no solution
