Question

Daniel is trying to determine the value of each of three variables: a, b, and c. How many equations must be in the system of equations if Daniel wants to solve for the value of each variable? Select one: A. One equation B. Two equations C. Three equations D. Cannot be determined from the information given

Answer 1

C. Three equations

Explanation:

The system of equations has to have the same number of equations as number of variables that the equations have, so for example if you want to solve an equation of three variables, you need a system of equations with 3 equations.

In this case you have three variables so you will need three equations in order to be able to solve this problem.

Answer 2

C. Three equations

Explanation:

In general, one independent equation is needed for each variable in a system. For a system with 3 variables, 3 independent equations are needed.
