Question

{X-5y=0
2x+y=110
Resolver

Answer 1

$x = 5y \\ 2x + y = 110 \\ 2x + 5y + y = 110 \\ y = 10 \\ 2x + 10 = 110 \\ x = 50 \\ (x.y) = (50.10) \\ 50 - 5x10 = 0 \\ 2x50 + 10 = 110 \\ 0 = 0 \\ 110 = 110 \\ (x.y) = (50.10)$

Answer 2

RESPOSTA

X-5Y=0 (-2)

2X+Y=110

-2X+10Y=-0

2X+Y=110

(-2X E O +2X VOCÊ CORTA)

11Y=110

Y=110÷11

Y=10

2X+Y=110

2X+(10)=110

2X+10=110

2X=110-10

2X=100

X=100÷2

X=50

S={Y=10,X=50}

espero ter ajudado!!
