Answer 1

An advantage of using equations for solving problems is that you can use algebra to manipulate the variables and constants in the equation to find the unknown value.

Step-by-step explanation:

An advantage of using equations for solving problems is that you can use algebra to solve the equation. Algebra allows you to manipulate the variables and constants in an equation to find the unknown value.

For example, if you have the equation 2x + 5 = 13, you can use algebraic steps to find the value of x. By subtracting 5 from both sides of the equation, you get 2x = 8. Then, by dividing both sides of the equation by 2, you find that x = 4.

Equations do not always need to be used with a table, graph, or diagram. While these tools can be helpful in understanding the problem, the equation itself contains all the necessary information to solve it.
