Question

7×-3y = -10
10x-3y = 164

Answer 1

Respuesta:

x = 58 y = 416/3

Explicación paso a paso:

7x -3y = -10(x10)

10x -3y =164(x-7)

70x - 30y = -100

-70x + 21y = -1148

-9y = -1248 => y = 416/3 x = 58

Comprobación:

7(58) - 3(416/3) = -10

406 - 416 = -10 => -10 = -10

10(58) - 3(416/3) = 164

580 - 416 = 164 => 164 = 164

RPTA: x = 58 y = 416/3
