```Hello Jamal,

for y in eqn1 identical with y in eqn2 try:

Clear[a, b, c, x, y];
eqn1 = x + x*a + x*a^2;
eqn2 = a*Sqrt[x] - b*x + c;
quot = Simplify[eqn1/eqn2]
Solve[quot == 1, x]
Solve[quot == 1, a]
Solve[quot == 1, b]
Solve[quot == 1, c]

to solve your system for your variables.

To analyse each equation use:

Solve[eqn1 == y, your variable]
Solve[eqn2 == y, your variable]

Dear Sir

My name is Jamal Elsanosi. I'm postgraduate student in petroleum
engineering in university of Miskolc-Hungary

I appreciate you if could help me to find the relationship between the
two equations
1-    y = x + x * a + x * a^2          and
2-    y = a * sqrt(x) - b * x + c

I'm looking for your reply in the earliest time

Best regards
Jamal Elsanosi
