Question

find the value of M: (2/9)4 *(2/9)-7=(2/9)2m+1

Answer 1

16/71=4m/9 +8
4/71=m/9+2
(4-71×2)/71=m/9
-138/71=m/9
m=(-138×9)/71
=-17.49

Answer 2

Hey friend,
Here is the answer you were looking for:
$( \frac{2}{9} )4 \times ( \frac{2}{9} ) - 7 = ( \frac{2}{9} )2m + 1 \\ \\ \frac{8}{9} \times \frac{2}{9} - 7 = \frac{4m}{9} + \frac{2}{9} \\ \\ \frac{16}{81} - 7 = \frac{4m + 2}{9} \\ \\ \frac{16 - 567}{81} = \frac{4m + 2}{9} \\ \\ \frac{551}{81} = \frac{4m + 2}{9} \\ \\ on \: cross \: multiplying \\ we \: get \\ \\ 81(4m + 2) = 551(9) \\ \\ 324m + 162 = 4959 \\ \\ 324m = 4959 - 162 \\ \\ 324m = 4797 \\ \\ m = \frac{4797}{324} \\ \\ m = 14.80(approx)$

Hope this helps!!!
