((3x – 8)/2x) = 1
(5x/(2x – 1)) = 2
((2x – 3)/(4x + 5)) = (1/3)
(8/x) = (5/(x – 1))
[(5(1 – x)) + (3(1 + x))/ (1 – 2x)] = 8
((0.2x + 5)/ (3.5x – 3)) = (2/5)
[(y – (4 – 3y))/ (2y – (3 + 4y))] = 1/5
(x/5) = (x – 1)/6
0.4(3x –1) = 0.5x + 1
8x – 7 – 3x = 6x – 2x – 3
10x – 5 – 7x = 5x + 15 – 8
4t – 3 – (3t +1) = 5t – 4
5(x – 1) – 2(x + 8) = 0
