Question

Решите уровнение срочно

Answer 1

2m + m(3-m-1) = 2m - m^2 +12
2m + 2m - m^2 - 2m + m^2 = 12
2m = 12
m = 6

2*6+6*(3-6-1) = 6*(2-6)+12
-12 = -12

Answer 2

2m +m( 3-m-1)=2m-m²+12
2m+3m-m²-m=2m-m²+12
2m+3m-m²-m-2m+m²=12
2m=12
m=6
Ответ 6

2*6 + 6(3-(6+1))=6( 2-6)+12
12+6*(-4)=6*(-4)=12
12-24=12-24
-12=-12
