Please i need your help for these problems:
1. if f(g(1/x)) = (x+2)x and f(x) and f(x)= 1/(3-x), find g(x).
2. Find the equation of the line through the origin and bisecting the angle between the axes in the first and third quadrants.
3. Find a so that the system below has an infinite number of solutions
ax + (2/3)y = 1/2
2x + (3/2)y = 9/8
