One matrix row operation
You are given the following matrix

Perform the following matrix operations:
1. $R_1\leftrightarrow R_2$
2. $R_2\leftrightarrow R_3$
3. $-4R_3$ → $R_3$
4. $3R_2$ → $R_2$
5. $R_1+R_2$ → $R_2$
6. $R_1+R_3$ → $R_3$
More than one matrix row operation
You are given the following matrix

Perform the following matrix operations:
1. $3R_1+2R_4$ → $R_4$
2. $2R_2-R_1$ → $R_2$
3. $-2R_3+R_1$ → $R_1$
4. $-2R_2+2R_3$ → $R_3$
