Solve for x.
(i) 3x - 5 = x + 5
(ii) 9x - 3 = 7x + 3
(iii)
(iv)

(i)3x - 5 = x + 5
3x - x = 5 + 5
2x = 10
x = 5
(ii) 9x - 3 = 7x + 3
9x - 7x = 3 + 3
2x = 6
x = 3
(iii)
3x + 2 = 8(2x - 3)
3x + 2 = 16x - 24
3x - 16x = -24 - 2
-13x = -26
x = 2
(iv)
28(3x - 8)=9(4x + 4)
84x - 224 = 36x + 36
84x - 36x = 36 + 224
48x = 260
x = 65/12
