Use addition to solve the linear system of equations. include all of your work in your final answer.
3x - y = 6
y = x - 4

Im not entirely sure this could work but rearrange the formula into a simultaneous equation so this for instance; (rearrange in another way if this isn’t entirely right)

3x-y=6

x+y=4

then same sign subtract them to give you y and x and plot or use to find the linear system.

Step-by-step explanation: Just from common knowledge, so sorry if this is wrong but give it a go.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

f is the midpoint of
