Question

Resolver equação fracionária considerando o conjunto R. (x + 2)/4 - 5/3 = (2x - 3)/3

Answer 1

$\frac{x + 2}{4} - \frac{5}{3} = \frac{2x - 3}{3} \\ 12 \times ( \frac{x + 2}{4} - \frac{5}{3} ) = 12 \times ( \frac{2x - 3}{3} ) \\ 3(x + 2) - 12 \times \frac{5}{3} = 4(2x - 3) \\ 3x + 6 - 4 \times 5 = 8x - 12 \\ 3x + 6 - 20 = 8x - 12 \\ 3x - 14 = 8x - 12 \\ 3x - 8x = - 12 + 14 \\ - 5x = 2 \\ x = - \frac{2}{5}$

Answer 2

Oie, Td Bom?!

(x + 2)/4 - 5/3 = (2x - 3)/3

12((x + 2)/4 - 5/3) = 12 . (2x - 3)/3

12 . (x + 2)/4 - 12 . 5/3 = 4(2x - 3)

3(x + 2) - 4 . 5 = 4(2x - 3)

3(x + 2) - 20 = 4(2x - 3)

3x + 6 - 20 = 8x - 12

3x - 14 = 8x - 12

3x - 8x = - 12 + 14

- 5x = 2

x = 2/-5

x = - 2/5
