Question:
In Problems 11–22, use elementary row operations to transform each augmented coefficient matrix to echelon form. Then solve the system by back substitution.
x_{1} + 3x_{2} + 3x_{3} = 13
2x_{1} + 5x_{2} + 4x_{3} = 23
2x_{1} + 7x_{2} + 8x_{3} = 29

I have done job as Embedded System Engineer for just four months but after it i have decided to open my own lab and to work on projects that i can launch my own product in market. I work on different softwares like Proteus, Mikroc to program Embedded Systems. My basic work is on Embedded Systems. I have skills in Autocad, Proteus, C++, C programming and i love to share these skills to other to enhance my knowledge too.
