Question

resolva as equações:


-2m ( -m+2 ) = 3 ( 2m+1 )


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


2 ( x-1 ) = 0


-3 ( m+2 ) = 1


2 ( x+2 ) = 12


m = -3 ( m-4 )


2 (m+5) = -3 ( m-5 )

Answer 1

Resposta:

Explicação passo-a-passo:

-2m ( -m + 2) = 3 ( 2m + 1)

2m - 4m = 6m+3

2m - 4m - 6m = 3

-8m = 3

m = -3/8

>>>>>>>

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

12m+3m-3=-4-2+12

15m=-4-2+12-3

15m=3

m=3/15 simplificando dividindo denominador e numerador por 3

m= 1/5

>>>>>>>

2 (x-1)=0

2x-2=0

2x=2

x=2/2

x=1

>>>>>>>>

-3 (m+2) = 1

-3m - 6 = 1

-3m = 1 + 6

-3m = 7

m = - 7/3

>>>>>>>

2( x+ 2)= 12

2x +4 = 12

2x = 12-4

2x= 8

x = 8/2

x= 4

>>>>>>>>

m= -3(m-4)

m = -3m +12

m+3m=12

4m= 12

m= 12/4

m= 3

>>>>>>>>>

2 ( m +5) = -3 ( m -5)

2m+10=-3m+15

2m+3m=15-10

5m= 5

m= 5/5

m= 1
