Question

7x+9/4-(x-2x-1/9)=7 solve the equation​

Answer 1

Here is your answer:

Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7. ... 3x + 3 = x + 13, 3x = x + 10, 2x = 10, and x = 5.

Answer 2

Answer:

$7x + \frac{9}{4} - (x - 2x - \frac{1}{9} ) = 7$

$7x + \frac{9}{4} - x + 2x + \frac{1}{9} = 7$

$7x - x + 2x + \frac{9}{4} + \frac{1}{9} = 7$

$9x - x + \frac{81 + 4}{36} = 7$

$8x + \frac{85}{36} = 7$

$8x = 7 - \frac{85}{36}$

$8x = \frac{252 - 85}{36}$

$8x = \frac{167}{36}$

$x = \frac{167}{288}$
