Answer to Problem 21WE
There is unique solution for the system.
Explanation of Solution
Given information:
Calculation:
Let a1 and a2 be the coefficients of variable p and b1 and b2 be the coefficients of variable q in both equations,
And,
So, system has unique solution.
subtracting equation 1 from 2,
Substitute 1/2 for q in equation 1,
the system has unique solution and the value of
