Total coins=46 There are 10 dimes, so it is 10/46. If you reduce it the answer is 5/23. That is not one of the visible options, but there is no option for B so I could be right!
X + y = 1.....multiply by -1 4x + y = -23 --------------- -x - y = -1 (result of multiplying by -1) 4x + y = -23 ---------------add 3x = - 24 x = -24/3 x = -8 <====
