Yamin had an odd number of socks in his drawer. He took one out of the pile, then divided the pile into six, so each new pile only had two socks in it. How many socks, did Yamin have in the first place? Write and solve an equation.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
