(2) When two sides of the equation form 2(x- 1), 2x = 3-4 (x- 1), 2x = 3-4x+4, 2x+4x = 3+4, 6x = 7 and x = 7/6.

(3) Multiply both sides of the equation by (2x- 1)(2x+ 1) to get 2 (2x+ 1) = 4, 4x+2 = 4, 4x = 4-2, x = 1/2.

(4) Multiply both sides of the equation by x(x+2)(x-2) to get 3 (x-2)-(x+2) = 0, 3x-6-x-2 = 0, 3x-x = 6+2, 2x = 8 and x = 4.

(5) Multiply both sides of the equation by (x-3)(x- 1) to get x (x- 1) = (x+ 1) (x-3), and x 2-x = x 2-2x-3, 2x-.

(6) Multiply (x-2) on both sides of the equation to get x-3+x-2 =-3, 2x =-3+3+2, 2x = 2, x = 1.

(7) Multiply both sides of the equation by 6x(x+ 1) to get 6 (2x+ 1) = 5x, 12x+6 = 5x, 12x-5x =-6, 7x =-6, and x =-6/.

(8) Multiply two sides of the equation by 2(3x- 1) to get 3 (3x- 1)-2 = 5, 9x-3-2 = 5, 9x = 5+3+2, 9x = 10, and x = 65438+.
