x=(3/4)y-5/8

please answer the entire question

(x^{3} + x^{2} + x - 3) ÷ (x - 1)

(3x^{3}y^{2}^-{2} •(18x^{8}y^{6}+ 4x^{2}y^{2}

x = (3/4)y - 5/8

|5 - 3x| + 3≤7

-2x + y + 6z = 1 3x + 2y + 5z = 16 7x + 3y - 4z = 11

x + 4y - 2z = 3 x + 3y + 7z = 1 2x + 9y + z = 8

x + 4y = 3 3x + 12y = 5

(1/3)x=(7/3)y+2
