Question

me ajudaaaaaaaaaaaaaaaaaaa

Answer 1

$43)$

a)
$\frac{x}{9} + \frac{y}{9} = \frac{9}{9} \\ \frac{x}{9} + \frac{y}{9} = 1$
b)
$\frac{3x}{5} + \frac{2y}{5} = \frac{5}{5} \\ \frac{x}{(3 \div 5} + \frac{y}{(2 \div 5)} = 1$

$c) \: \: \frac{3x}{12} + \frac{2y}{12} = \frac{12}{12} \\ \frac{x}{4} + \frac{y}{6} = 1$
$44)$
$a) \: \: \frac{x}{9} + \frac{y}{2} = 1$
$b) \: \: \frac{ x}{ - 3} + \frac{y}{ - 5} = 1$
$c) \: \: \frac{3}{ - 1} + \frac{2}{ - 6} =1 \\ \frac{x}{ - 3} + \frac{y}{ - 3} = 1$
