Question

resolver las siguientes ecuaciones​

Answer 1

Respuesta:

$a)a + ( - \frac{8}{3} ) = 23 \\ a - \frac{8}{3} = 23 \\ 3(a - \frac{8}{3} ) = 23 \times 3 \\ 3a - 8 = 69 \\ 3a = 69 + 8 \\ 3a = 77 \\ a = \frac{77}{3}$

$b)2y + ( - \frac{5}{4} ) = 0.75 \\ 2y - \frac{5}{4} = \frac{3}{4} \\ 4(2y - \frac{5}{4} ) = 4 \times \frac{3}{4} \\ 8y - 5 = 3 \\ 8y = 3 + 5 \\ 8y = 8 \\ y = 1$

$c)18x = \frac{1}{3} \\ 3 \times 18x = \frac{1}{3} \times 3 \\ 54x = 1 \\ x = \frac{1}{54}$

$d)m - 5 = \frac{2}{7} \\ 7(m - 5) = 7 \times \frac{2}{7} \\ 7m - 35 = 2 \\ 7m = 2 + 3 5\\ 7m =37 \\ m = \frac{37}{7}$
