Answer to Problem 19E
The solution is
Explanation of Solution
Given information:Given equations are
Formula used: Elimination method
Calculation:
Since the given equations are
Multiplying (1) by 2 and (2) by 3, then
Adding these equations
Also, multiplying (1) by 12 and (2) by 5, then
Subtracting these equations
Thus, the required solution is
Verification
Which is equal to right hand side.
Hence verified.
