Question

how does it become 9x = 81/13
plz Explain​

Answer 1

$9x = 12 - \frac{75}{13} \\ 9x = \frac{156 - 75}{13} \\ 9x = \frac{81}{13}$

This is the process how this happened

Answer 2

Answer:

its correct

Step-by-step explanatio

we have 9x = 12-(75/13)

we can make the demonitators same by multiplying and dividing the 12 by 13

then we get

9x =( $\frac{12*13}{13}$ ) -( $\frac{75}{13}$)

9 x = $\frac{156}{13}$  - ( $\frac{75}{13}$)

9x =  $\frac{156-75}{13}$  = $\frac{81}{13}$
