Question

12. Find the value of x
​

Answer 1

Question :-

_____________

$\frac{9x + 7}{2} - (x - \frac{x - 2}{7} ) = 36$

Answer :-

___________

$\frac{9x + 7}{2} - ( \frac{7x - x + 2}{7}) = 36 \\ \frac{9x + 7}{2} - ( \frac{6x + 2}{7} ) = 36 \\ \frac{63x + 49 - 12x - 4}{14} = 36 \\ \frac{51x + 45}{14} = 36 \\ 51x + 45 = 36 \times 14 \\ 51x + 45 = 504 \\ 51x = 504 - 45 \\ 51x = 459 \\ x = \frac{459}{51} \\ x = 9$

×=9
