Question

$\frac{2}{7} (x - 9) + \frac{x}{3} = 3$
what is the answer​

Answer 1

Answer:

Step-by-step explanation:

Given that,

2/7 (x - 9 ) + x /3 = 3

2 ( x - 9 ) / 7 + x / 3 = 3

( 2x - 18 ) / 7 + x / 3 = 3

[ 3 ( 2x - 18 ) + 7 ( x ) ] / 21 = 3

( 6x - 54 + 7x ) / 21 = 3

( 13x + 54 ) / 21 = 3

13x + 54 = 3 × 21 (since, transposing )

13x + 54 = 63

13x = 63 - 54 (since, transposing )

13x = 9

x = 9/ 13 is the answer.,. (Since, transposing )
