1. Problem Description
We are given a system of two linear equations with two variables, and :
Our goal is to find the values of and that satisfy both equations.
2. Solution Steps
We can solve this system of equations using the elimination method. Notice that the coefficients of in the two equations are and , so adding the two equations will eliminate .
Adding the two equations gives:
Now, we can solve for by dividing both sides by 9:
Now that we have the value of , we can substitute it into either equation to solve for . Let's use the second equation:
Subtract 12 from both sides:
Divide both sides by 6:
Therefore, the solution to the system of equations is and .
