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 solve this system of equations using the substitution or elimination method. Let's use the substitution method.
From the first equation, we can express in terms of :
Now, substitute this expression for into the second equation:
Now that we have the value of , we can substitute it back into the expression for :
Thus, .
We can check our solution by substituting and into both original equations:
, which is correct.
, which is also correct.
