Resolva as equações
3x-5=x+10
5-4x-2=8+2x-2​

Answer 1

Explicação passo-a-passo:

Resolva as equações

3x-5=x+10

3x-x= 10+5

2x= 15

x = 15/2

5-4x-2=8+2x-2

3-4x = 6+2x

3-6= 2x+4x

-3= 6x

(:3) 6x = -3 (:3)

2x = -1

x = -1/2

Answer 2

3x-5=x+10

3x-x=10+5

2x=15

x = 15/2



5-4x-2=8+2x-2

3-4x=6+2x

3-6=2x+4x

-3=6x

(:3) 6x=-3 (:3)

2x = -1

x= -1/2
