biaguxalindafop8lhqb $\frac{x + 2}{2} + \frac{x + 5}{3} = 7$
Tirando o MMC, temos: 6
$\frac{3x + 6 + 2x + 30}{6} = \frac{42}{6}$ (cortando os dois 6)
3x + 6 + 2x + 30 = 42
5x + 36 = 42
5x = 42 - 36
5x = 6
x = $\frac{6}{5}$

$\frac{x + 2}{2} - \frac{x + 5}{3} = 7$
Tirando o MMC, temos: 6
$\frac{3x + 6 - 2x + 30}{6} = \frac{42}{6}$ (cortando os dois 6)
3x + 6 - 2x + 30 = 42
x + 36 = 42
x = 42 - 36
x = 6
