An integer is between -4 and -19. It is twice as far from -4 as it is from -19. What is the integer? Explain how you know. I am very confused

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
