To find the values of and that satisfy the given system of linear equations, we can use the method of substitution. Let's write down the given equations:
and
First, we can express in terms of using the second equation by subtracting from both sides:
Next, we substitute this expression for into the first equation:
Now, we distribute the to simplify the equation:
Combine the like terms containing :
Subtract from both sides of the equation to isolate the term with :
Divide both sides by to find :
To find the corresponding value of , substitute the value of back into our expression for :
Simplify the multiplication:
Convert to a fraction with a denominator of to add the terms:
Thus, the final values are and .
