### Question Description

I don’t understand this Mathematics question and need help to study.

## Final Answer

*3x - y = - 8 ......................1*

*7x + 3y = - 72 ................2*

*multiplying eq 1 by3 and adding it with eq 2,then*

*9x - 3y = - 24*

*7x + 3y = - 72-------------------*

*16x = - 96*

*x = - 6*

*Now putting the value of x in first equation,then*

*3(- 6) - y = - 8*

*- 18 - y = - 8*

*18 + 8 = y*

*y = - 10*

*Solution = (-6, -10)*
