Answer:
Step-by-step explanation:
8x + 3 = 27 + 2x
By transposition,
⇒ 8x – 2x = 27 − 3
⇒ 6x = 24
⇒ x = 4
Q-2 5x + 7 = 2x - 8
By transposition,
⇒ 5x−2x = - 8 - 7
⇒ 3x = - 15
x=-5
Q-3 2z - 1 = 14 - z
By transposition,
⇒ 2z + z = 14 + 1
⇒ 3z = 15
Dividing by 3, on both the sides we get,
⇒ z = 5
Q-4 9x + 5 = 4(x - 2) + 8
By transposition,
⇒ 9x + 5 = 4x - 8 + 8
⇒ 9x - 4x = - 5 + 0
⇒ 5x = - 5
⇒ x = - 1
