If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values so the are no solutions
4/5 x55
=4/5*55/1
=(4*55)/(5*1)
=220/5
=44/1
=44
It is 8.525. what u do is 21÷40 and get .525 and then u add the 8 in the front and get 8.525
