Answer 2

Resposta:

x=60/13

Explicação passo-a-passo:

x/3 + x/10 +1=3

x/3 + x/10 +1=3

30(x/3 + x/10 +1)=30×3

30× x/3 + 30× x/10 +30=30×3

30(x/3 + x/10 +1)=30×3

30× x/3 +30× x/10 +30=90

30× x/3 +30× x/10 +30=90 aqui risque os numeros 30 e 3.

10x+30× x/10 +30=90

30× x/3 +30× x/10 +30=90aqui risque os numeros 30 e 10.

10x+3x+30=90

x/3 + x/10 +1=3

10x+3x+30=90

10x+3x

(10+3)x

13x

10x+3x+30=90

13x+30=90

13x+30-30=90-30

13x=90-30

13x+30=90

13x=90-30

13x=60

13x÷13=60÷13

x=60÷3

13x÷13=60÷13

x=60÷13

13x÷=60÷13

x=60/13

13x=60

x=60/13
