Given:

The leading coefficient of the first equation is 70.

The leading coefficient of the second equation is 50.

The leading coefficient of the third equation is 65.

Required:

We need to divide each row by the leading coefficient.

Step-by-step explanation:

Divide the first row of the augmented matrix by 70.

$(1)/(70)R_1\rightarrow R_1$

Divide the second row of the augmented matrix by 50.

$(1)/(50)R_2\rightarrow R_2$

Divide the third row of the augmented matrix by 65.

$(1)/(65)R_3\rightarrow R_3$

Final answer:

$(1)/(70)R_1\rightarrow R_1$
$(1)/(50)R_2\rightarrow R_2$
$(1)/(65)R_3\rightarrow R_(3-)$
