HEL hello just a disguised question lol

but

THERE'S SO MANY QUESTIONS COMING IN

I THINK IT'S BECAUSE SCHOOL'S ALMOST OUT FOR SUMMER

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

What is the value of the discriminant of the quadratic equation -2x = -8x + 8 and what does its value mean about thenumber of real number solutions the equation has?

Multiply and simplify. (x - 4) (x^2 – 5x – 6) i will mark brainliest if your answer is right. show how you got the answer. if your answer is correct but does not show how you got the answer you will not be marked brainliest.
