Question

Verify that -(-y)=y for y = -9÷13

Answer 1

Step-by-step explanation:

$y \: = \frac{9}{13} \\ mimus \: \times minus \: = plus \\ bracket \: means \: multiplicatiom \\ so \: - ( - \frac{9}{13}) = \frac{9}{13} \\ \frac{9}{13} = \frac{9}{13} \\ hence \: \: - ( - \frac{9}{13} ) = \frac{9}{13}$
