Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

(-2,0.2)

Step-by-step explanation:  

we have

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The intersection points are (-1.9,0.2) and (1,6)

see the attached figure

therefore

The solution of the system of equations are the points (-1.9,0.2) and (1,6)

idk

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
