Question

найдите корень уравнения ( 8m + 97)\3 - 3 = 8

Answer 1

$\frac{8m+97}{3} -3=8 \\ \frac{8m+97}{3} - \frac{9}{3} =8 \\ \frac{8m+88}{3} =8 \\ 8m+88=8*3 \\ 8m+88=24 \\ 8m=-64 \\ m=-8$

Answer 2

(8м + 97) / 3 - 3 = 8
(8м + 97) / 3 = 8 + 3
(8м + 97) / 3 = 11
8м + 97 = 11 х 3
8м + 97 = 33
8м = 33 - 97 
8м = - 64
м = - 64 : 8
м = - 8
