Answer 1

Explicação passo-a-passo:

$\frac{x + 2}{4} + \frac{x + 3}{5} = 2 \\ tira \: mmc \: dos \: denominadores \\ \frac{ \frac{20}{4} \times (x + 2) + \frac{20}{5} \times (x + 3) }{20} = 2 \\ \frac{5 \times (x + 2) + 4 \times (x +3 )}{20} = 2 \\ 5x + 10 + 4x + 12 = 2 \times 20 \\ 9x + 22 = 40 \\ 9x = 18 \\ x = \frac{18}{9} = 2$

Answer 2

$\frac{x + 2}{4} + \frac{x + 3}{5} = 2 \\ \frac{5(x + 2) + 4(x + 3)}{20} = 2 \\ 5(x + 2) + 4(x + 3) = 2 \\ 5x + 10 + 4x + 12 = 2 \\ 9x + 22 = 2 \\ 9x = 2 - 22 \\ 9x = - 20 \\ x = \frac{ - 20}{9}$
