Question

9x+7/2 -[x-(x-2/7)]=36 Ans.=9 but how

Answer 1

Answer:

451/51

Step-by-step explanation:

9x+7/22-(7x-1(x-2)/2)=36

Answer 2

Given:

$\frac{9x+7}{2}-[x-(\frac{8-2}{7}) ] = 36$

To Find:

value of x

Solution:

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

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

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

⇒$\frac{9x+7}{2}-\frac{6x+2}{7} = 36$

⇒ $7\frac{9x+7}{14}- 2 (6x+2)=36$

⇒63x + 49 - 12x- 4 = 504

⇒51x + 45 = 504

⇒51x = 504- 45

⇒51x = 459

⇒x = 459/51

⇒ x = 9

Therefore, the value of x is 9.
