The value of x and y is and
Step-by-step explanation:
Let x denote the sodas.
Let y denote the bags of popcorn.
Given: Kaelyn bought a soda and two bags of popcorn for $3. Writing this as equation,
Her brother bought three sodas in a bag of popcorn for $6.50. Writing this as equation,
Using substitution method, let us find the value of x from the equation by subtracting 2y from both sides of the equation, we get,
Now, substituting the value of x in , we get,
Subtracting 9 from both sides of the equation, we get,
Now, substituting the value of in , we get
Thus, the value of x and y is and
