The given system of equation need to solve by using the substitution method:
Answer to Problem 5E
The solutions of set of eqns.
Explanation of Solution
Given:
Concept Used:
If in the system of equations, there are two variables are used and they said that need to solve the system of equations with the help of the substitution method then one need to rewrite the one equation out of two to get one variable value.
Then put this variable value into the second eq. then the new eq. will find which is used to find another value of second variable. Now, you will get the exact value of the second variable, use it to find the first variable.
Calculations:
The given eqns. are:
Put the value of
Now, to find the value of
So, the solutions of given set of eqns. is
Conclusion:
Hence, the solutions of given set of eqns. is:
