Question

Describe the first step you would take to solve the system of equations 8x + y = -16 and - 3x + y = -5 using elimination and justify your answer.

Answer 1

8x + y = -16

3x + y = -5

The first to take is to subtract the second equation from the first equation

This will eliminate the y-variable leaving you with jus x-variable

That is;

5x = -11

x = -11/5
