Question:
In Example 2, change the right side of the second equation from 2 to 3 and then solve the system.
Data from Example 2
By substitution, solve the system of equations
From the first equation, we have y = −2/x. Substituting this into the second equation, we have
By substituting these values for x into either of the original equations, we find the corresponding values of y, and we have the solutions
These can be checked by substituting in the original equations. In decimal form, they are x ≈1.618, y ≈ −1.236 and x ≈ −0.618, y ≈ 3.236
The graphical solutions are shown in Fig. 14.10.
