02.
e) o.
d).I.​

Answer 1

Explicação:

$+ 2 \times 5 x + 1 - 8x + 2 + 8x = 16x + 2 + 8x \\ 2 \times 5x + 1 + 2 = 16x + 2 + 8x \\ 2 \times 5x + 1 + 2 - 5x = 16x + 2 + 8x - 5x \\ 2 \times 1 + 2 = 19x + 2 \\ 2 \times 1 + 2 = 19x + 2 - 2 \\ 2 -\times 1 + 2 - 2= 19x \\ (2 \times 1 + 2 - 2) \ \div 9 = 19x \div 9 \\ (2 \times 1 + 2 - 2) \div 9 = 1x \\ 2 \div 9 = x \\ 0.2222222222 \: ou \: 0.22 = x$
