Answer:
The solution (a,c) is (0.46, 5.27)
Explanation:
Let's write down the system
To solve this system we are going to use the method of reduction, we are going to multiply the second equation by -22 so that our a's disappear when we sum up the equations.
Multiplying by -22 we get:
Now if we sum up both equations we have:
Now we substitute c in our second equation:
Thus, the solution (a,c) is (0.46, 5.27)
