Question

Alguem me ajuda porfavor
142+24=10R+2R+30?

Answer 1

$A=B\rightarrow\,B=A$

$\mathsf{142+24=10R+2R+30}\\\mathsf{10R+2R+30=142+24}\\\mathsf{12R=166-30}$

$\mathsf{12R=136}\\\mathsf{R=\dfrac{136\div4}{12\div4}}\\\mathsf{R=\dfrac{34}{3}}$

Answer 2

Resposta:

Explicação passo-a-passo:

142 + 24 = 10R + 2R + 30

-10R -2R = +30 - 142 - 24

-12R = - 136 (-1)

12R = 136

R = 136/12 = 68/6 = 34/3
