(-3,-2)

(4,0)

(5,4)

(-7,-8)

The solution of this system of linear equations is .

Step-by-step explanation:

Let be the following system of linear equations:

(1)

(2)

From (1) we clear :

And we apply this variable in (2):

And the value of is:

The solution of this system of linear equations is .

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
