24) Using the properties of proportion, solve the following equations:
63 (1 - x)
x + 3x
3x2 + 1
√x + 2+ √x-2
(i)
√x+2 - x - 2
(1 + x + x2)
(1 - x + x2)
= 5
5x + (x2 - 1) 7
(ii)
5x – (x² - 1)
49 (1 + x
25) If x =
2a + 1 + 2a - 1
show thatx2 - 4ax + 1 = 0
2a +1-72a-1'
Va + 3b + Va - 3b
show that3bx- 2ax + 3b = 0
