Answer to Problem 42S
The solution set of the system of equations is
Explanation of Solution
Given information:
The system of equations is provided below,
Formula used:
A system of equations with two variables can be solved by elimination method and substitution method.
In elimination method, multiply the equations to make the constant term equal of same variable and then add or subtract them to solve.
In substitution method, substitute the value of one variable from first equation into second and simplify it further.
Calculation:
Consider the provided system of equations as,
Recall that a system of equations with two variables can be solved by elimination method and substitution method. In substitution method, substitute the value of one variable from first equation into second and simplify it further.
Apply it,
Substitute the value of yi .e.
Now substitute
Thus, the solution set of the system of equations is
