Question

Q-Find the value ofx for the following equations. a) 2x - 1 = x b) 4x + 19 = x + 22 c) 3 + x = 4x - 3 d) 8x + 1 = 15 + x -​

Answer 1

Answer:

Step-by-step explanation:

a) 2x-1=x

⇒2x- x = 1 (transposing)

x = 1

b) 4x + 19 = x + 22

⇒ 4x - x = 22 - 19 (∵ transposing )

⇒ 3x = 3

⇒ x = 3 / 3 (∵ transposing )

⇒ x = 1

c) 3 + x = 4x - 3

⇒ 3 + 3 = 4x - x (∵ transposing )

⇒ 6 = 3x

⇒ 6 / 3 = x (∵ transposing )

⇒ 2 = x

⇒ x = 2

d) 8x + 1 = 15 + x

⇒ 8x - x = 15 - 1 (∵ transposing )

⇒ 7x = 14

⇒ x = 14 / 7 ( ∵ transposing )

⇒ x = 2
