Answer 2

Answer:

Hello

Step-by-step explanation:

$3x + 2 = 2.2 \\ 3x + 2 = \frac{22}{10} \\ 3x + 2 = \frac{11}{5} \: \: (22 \times 2 = 11 \\ 2 \times 5 = 10) \\ 3x = \frac{11}{5} - 2 = \frac{11 - 10}{5} = \frac{1}{5} \\ 3x = \frac{1}{5} \\ x = \frac{1}{5} - 3 \\ x = \frac{1 - 15}{5} (5 \times 3 = 15) \\ x = 1 - 3 = - 2 \\ x = - 2$
