Question

2x+20(35x-3x)=40
follow me for this type questions and point.​

Answer 1

2x + 20(35x-3x) = 40

=> 2x + 20(32x) = 40

=> 2x + 640x = 40

=> 642x = 40

=> x= 40/642 = 20/321

Answer 2

..QUESTION..

Solve :

➪ 2x + 20 ( 35x - 3x ) = 40

..ANSWER..

Given equation :

ㅤㅤ➪ 2x + 20 ( 35x - 3x ) = 40

★ Solution :

➪ 2x + 20 ( 35x - 3x ) = 40

➪ 2x + 700x - 60x = 40

➪ 702x - 60x = 40

➪ 642xㅤㅤㅤ= 40

➪ x ㅤㅤㅤㅤ= 40 / 642

•°• x = 40/642

_____________________

proof of the equation :

°•° x = 40 / 642

•°• L.H.S =

= 2x + 20 ( 35x - 3x )

= 2 × 40/642 + 20 ( 35×40/642 - 3×40/642 )

= 80/642 + 20 ( 1400/642 - 120/642 )

= 80/642 + 20 [ ( 1400 - 120 ) / 642 ]

= 80/642 + 20 ( 1280 / 642 )

= 80/642 + 25600/642

= ( 80 + 25600 ) / 642

= 25680 / 642

= 40 = R.H.S
