Answer 1

Respuesta:

$11 {y}^{4} + 33$

Explicación paso a paso:

$- 5 {y}^{4} - 6 {y}^{4} + 9 \times 2 + 5 \times 3 \\ - 5 {y}^{4} - 6 {y}^{4} \\ - 11 {y}^{4} + 9 \times 2 + 5 \times 3 \\ 9 \times 2 = 18 \\ - 11 {y}^{4} + 18 + 5 \times 3 \\ 5 \times 3 = 15 \\ - 11 {y}^{4} + 18 + 15 \\ 18 + 15 = 33 \\ = - 11 {y}^{4} + 33$
