(vii)
Given : (2x/5 + 3)/ (x/3 - 1) = 3/5
⇒ 5(2x/5 + 3) = 3(x/3 - 1)
⇒ 2x + 15 = x - 3
⇒ x = -18.
(viii)
Given : (2x - 3/4)/(3x + 4/5) = 1/5
⇒ 5(2x - 3/4) = (3x + 4/5)
⇒ 10x - 15/4 = 3x + 4/5
⇒ 10x = 3x + 91/20
⇒ 7x = 91/20
⇒ x = 13/20.
(ix)
Given : (3x/4 + 1)/(x + 1/5) = 7/4
⇒ 4(3x/4 + 1) = 7(x + 1/5)
⇒ 3x + 4 = 7x + x/5
⇒ -4x = -13/5
⇒ x = 13/20.
Hope it helps!
