Question

3x+2(x−2)−20=2x−5 = ____ solve this equation ​

Answer 1

Answer:

Step-by-step explanation:

3x + 2 ( x - 2 ) - 20 = 2x - 5

⇒3x + 2x - 4 - 20 = 2x - 5 ( ∵ + × - = - )

⇒5x - 24 = 2x - 5 ( ∵ 3x + 2x = 5x )

⇒ 5x - 2x = 24 - 5 ( ∵ transposing )

⇒ 3x = 19

⇒ x = 19 / 3 is the answer. ( ∵ transposing )
