Hello,
7x + 17 = x + 9
7x - x = 9 - 17
6x = 8
x = 8/6 = 4/3
4x + 15 = 7x + 24
4x - 7x = 24 - 15
-3x = 9
x = -9/3 = -3
2x + 4 - x = 13
x + 4 = 13
x = 13 - 4
x = 9
5(x - 2) = 7x
5 * x + 5 * -2 = 7x
5x - 10 = 7x
5x - 7x = 10
-2x = 10
x = -10/2 = -5
3(5x + 2) + 1 = x
3 * 5x + 3 * 2 + 1 = x
15x + 6 + 1 = x
15x + 7 = x
15x - x = -7
14x = -7
x = -7/14 = -1/2
