Question 2 (20 points) Write an equivalent form of the equation where it is factored completely. 2x + 7x - 15 a b (x - 3)(x + 10 (2x - 3)(x + 5) (2x - 3)(x - 5) (x-3)(x - 10) Ос​

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

X+ y = 5 ; x - y =3 solve using linear combination
