5x - 19 = 24x - (3x + 13)
5x - 19 = 24x - 3x - 13
5x - 19 = 21x - 13
21x - 5x = -19 + 13
16x = -6
x = -6/16
x = (-3 * 2)/(8 * 2)
x = -3/8
6 + 2(8 + 6x) - 9(3x + 4) = 0
6 + 16 + 12x - 27x - 36 = 0
-15x - 14 = 0
15x = -14
x = -14/15
2x + (4 + 3x)/5 = 2 - (x - 6)/10
(2x * 10) + 2(4 + 3x) = 2 * 10 - x + 6
20x + 8 + 6x = 20 - x + 6
26x + 8 = 26 - x
26x + x = 26 - 8
27x = 18
x = 18/27
x = (2 * 9)/(3 * 9)
x = 2/3
(7x - 14)/21 - 39/52 = 5x/30
7(x - 2)/(7 * 3) - (3 * 13)/(4 * 13) = 5x/(6 * 5)
(x - 2)/3 - 3/4 = x/6
4(x - 2) - 3 * 3 = 2x
4x - 8 - 9 = 2x
4x - 2x = 17
2x = 17
x = 17/2
(3x - 7)/8 - (5x - 1)/16 = (3 - 2x)/4 - 1
2(3x - 7) - (5x - 1) = 4(3 - 2x) - 16
6x - 14 - 5x + 1 = 12 - 8x - 16
x - 13 = -8x - 4
8x + x = 13 - 4
9x = 9
x = 9/9
x = 1
