we are given the equations

x^2 = (y^2) +4

(x+0.95)^2 = ((y+1.05) ^2) +4

2.1y = 1.9x - 0.2

The question is to form a quadratic for x and then solve it and then find out terms for y.

I expanded out the second equation to y^2 - x^2 + 2.1y - 1.9x = -4.2

h/e everytime i try and replace a y value i end up with -4.2 = -4.2 or something similar.

It was based on 2 right angle triangles, first with sides 2, x, y

second with sides 2 , x + 0.95, y + 1.05

Thanks for any help in advance
