Solve each of the following equations and check your answers.
(a) −9(3x −8) −8(9 − 7x) = 5 + 4(9x +11)
(b) 21x − 4 – 7 (5x − 6) = 8x − 4(5x − 7)
(c) 5/7x + ½ = 5/14 + 2/3 x
(d) 4x/3 + 2 = 9/8 – x/6
(e) 7/6 (6x -7) – 3/8 (7x + 15) = 25
(f) 5/9 (7 – 6x) – ¾ (3 – 15x) = 1/12 (3x – 5) – 1/2
(g) 5/6 (4x -3) -2/5 (3x + 4) = 5x – 16/15(1 – 3x)
