Answer to Problem 35E
The solution for the given equations is
Explanation of Solution
Given information:
The given pair of equations are
Concept used:
The given equations are in two variables and can be solved graphically or algebraically. As these equations are simple and they can be solved by elimination method.
Calculation:
The elimination method is as follows.
Multiply the second equation by 5 to produce coefficients of y that differ only in sign.
Now simplify these equations and we get,
Now add the equations together, cancelling out the y variable.
Now as we know the x variable, we can solve for y by substituting it in any of the equations above.
Conclusion:
The solution for the given equations is
