Question

2x + 5y = 16 x: 1 , 3 , 5
x + 3y = 6 y: 1, 3 ,5

Answer 1

Respuesta:

2x + 5y = 16

2(1) + 5y = 16 2(3) + 5y = 16 2(5) + 5y = 16

2 + 5y = 16 6 + 5y = 16 10 + 5y = 16

5y = 16 - 2 5y = 16 - 6 5y = 16 - 10

5y = 14 5y = 10 5y = 6

y = 14/5 y = 10/5 y = 6/5

y = 2

Explicación paso a paso:

x + 3y = 6

x + 3(1) = 6 x + 3(3) = 6 x + 3(5) = 6

x + 3 = 6 x + 9 = 6 x + 15 = 6

x = 6 - 3 x = 6 - 9 x = 6 - 15

x = 3 x = -3 x = -9
