योग

उत्तर

x = p + 1 and `2.5 + (2"p" + 1)/(3)` = 1.5(2x - 1)

⇒ `2.5 + (2"p" + 1)/(3)` = 1.5[2(p + 1) - 1]

⇒ `2.5 + (2"p" + 1)/(3)` = 3(p + 1) -1.5

⇒ `2.5 + (2"p" + 1)/(3)` = 3p + 3 - 1.5

⇒ `2.5 + (2"p" + 1)/(3)` = 3p + 1.5

⇒ `(2"p" + 1)/(3) - 3"p"` = 1.5 - 2.5

⇒ `(2"p" + 1 - 9"p")/(3)`  = -1

⇒ 2p + 1 - 9p = -3
⇒ -7p = -3 - 1
⇒ -7p = -4

⇒ p = `(4)/(7)`.
