Math Problem Statement
Write the system of linear equations that is represented by the given augmented matrix. Assume that the variables are x1 and x2. [3 6 | 2] [1 4 | 9]
Solution
The augmented matrix given is:
3 & 6 & | & 2 \\ 1 & 4 & | & 9 \\ \end{bmatrix}$$ This represents a system of linear equations where the first row corresponds to the coefficients of $$x_1$$ and $$x_2$$ in the first equation, and the second row corresponds to the coefficients of $$x_1$$ and $$x_2$$ in the second equation. The system of linear equations is: $$3x_1 + 6x_2 = 2$$ $$x_1 + 4x_2 = 9$$ Would you like more details or clarification on any step? Here are 5 related questions for further practice: 1.
