Answer:

Hello! Here is your answer

Step-by-step explanation:

112=4(28)

a=4b

You can only have one variable so:

Combine b to a:

a-b=84

4b-b=84

Divide both sides by 3:

3b/3=84/3

b=28

But that is not it:

Sum of both cards:

a+b

a=112

b=28

112+28=140

= 140

I hope I was of help. If not please let me know! Thank you! Good luck!

Anna [14]

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
