Answer 1

Hola!

Respuesta:

$a + b = 8$

Explicación paso a paso:

$a \: 0 \: 0 + a \: a + b \: 0 \: 0 + b \: b = 8 \: 8 \: 8 \\ (100 \times a) + (10 \times a + a) + (100 \times b) + (10 \times b + b) = 8 \: 8 \: 8 \\ 100a + 10a + a + 100b + 10b + b = 8 \: 8 \: 8 \\ 111a + 111b = 8 \: 8 \: 8 \\ 111(a + b) = 8 \: 8 \: 8 \\ (a + b) = \frac{8 \: 8 \: 8}{1 \: 1 \: 1} \\ (a + b) = 8 \:$
