Question

3- Resolva as equações 4y + 2 = 8y-4 e 2x-2=3x + 4 e determine:​

Answer 1

$\LARGE{}4y + 2 = 8y - 4 \\ \LARGE{}4y + 2 - 8y = - 4 \\ \LARGE{}4y - 8y = - 4 - 2 \\ \LARGE{} - 4y = - 4 - 2 \\ \LARGE{} - 4y = - 6 \\ \LARGE\boxed{y = \frac{3}{2} }$

$\LARGE{}2x - 2 = 3x + 4 \\ \LARGE{}2x - 2 - 3x = 4 \\ \LARGE{}2x - 3x = 4 + 2 \\ \LARGE{} - x = 4 + 2 \\ \LARGE{} - x = 6 \\ \LARGE{} - 1 \times ( - x) = - 1 \times 6 \\ \LARGE{}x = - 1 \times 6 \\ \\ \LARGE\boxed{x = - 6}$
