Final answer:
To solve the system for y, substitute a=1/x and b=1/y into the equations, solve for b, then find y as the reciprocal of b, y=1/b.
Step-by-step explanation:
The system of equations presented can be solved using the substitution method hinted at, where a=1/x and b=1/y. After this substitution, the equations become linear in terms of a and b. Once a and b are solved for, we can find the values of x and y by converting back, namely, x=1/a and y=1/b.
If you want a solution for y, and you have solved for b, then y is simply the reciprocal of b. Therefore, y=1/b. Following this step, the solution for y can be substituted back into the original equations to find the value of x.
