Question

3(x-3)-1=2

3(x+2)=2(x-7)

6x+3(x+1)-7=2(2x-1)-(1-x)
Urgente ☹️

Answer 1

Explicação passo-a-passo:

3(x-3)-1=2

3x-9-1=2

3x=2+1+9

3x=12

x=12/3

x=4

3(x+2)=2(x-7)

3x+6=2x-14

3x-2x=-14-6

x=-20

6x+3(x+1)-7=2(2x-1)-(1-x)

6x+3x+3-7=4x-2-1+x

6x+3x-4x-x=-2-1+7-3

4x=1

x=1/4 ou x=0,25
