1. Problem Description
We are given a system of two linear equations with two variables, and :
We need to find the values of and that satisfy both equations.
2. Solution Steps
We can use the elimination method to solve this system of equations. First, we multiply the first equation by 1 and the second equation by -3 to eliminate the variable:
Equation 1:
Equation 2:
Multiply Equation 1 by 1:
Multiply Equation 2 by -3:
Now add the modified equations:
Divide by -13 to solve for :
Now that we have the value of , we can substitute it back into either of the original equations to solve for . Let's use the second equation:
Thus, and .
3. Final Answer
The solution is and .
