If (a + b / 10) = (a - 0.1b^2 / a - b), what is the value of a?

F. 0.001
G. 0.1
H. 1
J. 10
K. 100

If you follow the rules of PEDMAS, what you wrote means:

a + (b/10) = a - (0.1b^2/a) -b

Please confirm if you really mean

if(a+b)/10 = (a-0.1b²)/(a-b)

Also, post what your answer is, and explain.
