Final Answer:
The correct keyword used to solve linear equations in SAS is "SOLVE" (option a). a) SOLVE
Step-by-step explanation:
In SAS, the SOLVE statement is specifically designed for solving linear equations. When dealing with linear systems, the SOLVE statement is crucial for obtaining solutions efficiently and accurately.
In SAS, the SOLVE statement simplifies the process of solving linear equations by providing a straightforward and effective means of obtaining solutions. This keyword is particularly useful when dealing with regression models or other situations where the solution of a linear system is required. Utilizing the SOLVE statement in SAS simplifies the coding process and enhances the clarity of the program, making it a preferred choice for addressing linear equations.
To implement the SOLVE statement in SAS, one typically specifies the linear equations to be solved, and the SOLVE statement then calculates and assigns the values to the variables involved in the equations. This enhances the ease of analysis and ensures that SAS users can efficiently handle linear systems in their programming. Therefore, the correct choice for solving linear equations in SAS among the given options is indeed "SOLVE" (option a).
