Question

it is of linear equations

Answer 1

Hey !!

Given -

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

---> (2x-18)/7 + x/3 = 3
---> [ 3(2x-18) + 7x ]/21 = 3
---> 6x - 54 + 7x = 63
---> 13x = 63+54
---> 13x = 117
---> x=9

Hence , x=9 Ans.

Hope it helps you :)

Answer 2

Dear friend,

$\frac{2}{7}(x - 9) + \frac{x}{3} = 3$

$\frac{2x - 18}{7} + \frac{x}{3} = 3$

$\frac{3(2x - 18) + 7x}{21} = 3$

$\frac{6x - 54 + 7x}{21} = 3$

$\frac{13x - 54}{21} = 3$

$13x - 54 = 63$

$13x = 117$

$x = \frac{117}{13}$

$x = 9$

Answer. x is 9.

Hope it helps !!!
