Question

2. 11y-5y+6=-2-9y ecuaciones de primer grado

Answer 1

Explicación paso a paso:

$11y - 5y + 6 = 2 - 9y \\ 6y + 6 = 2 - 9y \\ 6y + 9y = 2 - 6 \\ 15y = - 4 \\ y = - \frac{4}{15} \\ \\ comprobacion \\ 11 \times (- \frac{4}{15} ) - 5 \times ( - \frac{4}{15} ) + 6 = 2 - 9 \times ( - \frac{4}{15} ) \\ \\ - \frac{44}{15} + \frac{20}{15} + 6 = 2 + \frac{36}{15} \\ \\ - \frac{24}{15} + 6 = \frac{30 + 36}{15} \\ \\ \frac{ - 24 + 90}{15} = \frac{66}{15} \\ \\ \frac{66}{15} = \frac{66}{15} \\ \\ \frac{22}{5} = \frac{22}{5}$
