Question

9x+7/2-(x-x-2/7)=36​

Answer 1

Answer:

X=7.2

Step-by-step explanation:

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

9x+7/2-x-x-2/7=36

9x-x-x+7/2-2/7=36

7x+5/7=36

7x=36x7/5

x=252/35

x=7.2

Answer 2

Step-by-step explanation:

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