x=1/5

Explicação passo-a-passo:

-3x+10=2x+8+1

-3x+10=2x+8+1

3x+10=2x+9

-3x+10-2x=2x+9-2x

-3x+10-2x=9

-3x+10=2x+9

-3x+10-2x=9

-3x+10=2x+9

-3x-10-2x-10=9-10

-3x-2x=9-10

-3x+10=2x+9

-3x-2x=9-10

-3x-2x

(-3-2)x

-5x

-3x-2x=9-10

-5x=9-10

-3x-2x=9-10

9-10

-(10-9)

-1

-3x-2x=9-10

-5x=-1

-5x÷(-5)=-1÷(-5)

x=-1÷(-5)

-5x÷(-5)=-1÷(-5)

x=1÷5

-5x÷(-5)=-1÷(-5)

x=1/5

-5x=-1

x=1/5
