A word problem is a situation that presents a scenario with a set of information and asks a question about the relationship between different quantities. To solve this problem, we can use algebraic equations to represent the unknowns involved and then solve for the unknown variable(s).
Let's consider the following example:
John has 5 apples and 3 oranges. He also has 2 bananas. How many fruits does he have in total?
Step 1: Define the unknowns
Let x represent the number of apples John has.
Let y represent the number of oranges he has.
Let z represent the number of bananas he has.
Step 2: Set up algebraic equations
We can create the following equations based on the information provided:
x + y + z = 5 (since he has 5 apples and 3 oranges and 2 bananas)
x = 5 - y (since he has 5 apples and 3 oranges but no bananas)
z = 2 (since he has 2 bananas)
Step 3: Solve the equations
We can solve these equations using various methods like substitution, elimination, or balancing. After solving the equations, we find that y = 2 and z = 2. Therefore, John has 5 apples, 2 oranges, and 2 bananas.
Key takeaway:
Solving word problems with algebraic equations requires us to represent the unknowns using variables, set up corresponding equations based on the information provided, and solve those equations to find the unknown values
