Question

Alguem me ajuda porfavor

Answer 1

Resposta:

$x + 28 = 11 \\ x = - 17$

$2x - 5 = x + 1 \\ x = 6$

$5x + 7 = 4x + 10 \\ x = 3$

$3(x - 2) = 2x - 4 \\ x = 2$

$3(x - 1) - 7 = 15 \\ x = \frac{25}{3}$

$5x - 3(x + 2) = 15 \\ x = \frac{21}{2}$

$\frac{3x}{4} - \frac{x}{3} = 5 \\ x = 12$

$\frac{2x - 7}{5} = \frac{x + 2}{3} \\ x = 106$

$3(x - 2) = 4(x + 3) \\ x = - 18$

$5(x + 1) - 3(x + 2) = 0 \\ x = \frac{1}{2}$

$7x + 8 = 4x - 10 \\ x = - 6$

$2(3 - x) = 3(x - 4) + 15 \\ x = \frac{3}{5}$

$84 = 6x \\ x = 14$

$6x = 2x + 16 \\ x = 4$
