Question

5x+2y=15 10x-4y=10 ayuda ​

Answer 1

Respuesta:

$5 x + 2y = 10 \\ 1510x - 4y = 10 \\ 5x + 2y = 10 \\ 755x - 2y = 5 \\ 760x = 15 \\ x = \frac{3}{152} \\ 5x \frac{3}{152} + 2y = 10 \\ y = \frac{1505}{304} \\ (x.y) = ( \frac{3}{152} . \frac{1505}{304} ) \\ 5 = \frac{3}{152} + 2x \frac{1505}{304} = 1510x \frac{3}{152} - 4x \frac{1505}{304} = 10 \\ 10 = 10 =10 \\ (x.y) = ( \frac{3}{152} . \frac{1505}{304} )$
