[2x - 3 = 5]
2x = 5 + 3
x = 8 / 2
x = 4
[3x - 1 = x + 9]
3x - x = 9 + 1
2x = 10
x = 10 / 2
x = 5
[5 - x = 2]
5 - 2 = x
x = 3
[(3x - 1) / 5 = 4]
3x - 1 = 4 * 5
3x = 20 + 1
x = 21 / 3
x = 7
[3x / 2 + 4 = 7]
3x + 4*2 = 7*2
3x = 14 - 8
x = 6 / 3
x = 2
[2x / 3 - 5 = 1]
2x / 3 = 1 + 5
2x = 6*3
x = 18 / 2
x = 9
[2x = 8 / x]
2x*x = 8
2x² = 8
x² = 8/2
x = V¯4
x = 2
[(2x–1)/3 + x/2 = 9]
2·(2x–1) + 3x = 6·9
4x–2 + 3x = 54
7x = 54+2=56
x = 56/7
x = 8
