Question

respuesta de ecuacion2x1 + 4x2 + 6 x3 = 18 4x1 + 5x2 + 6 x3 = 24 2x1 + 7x2 + 12x3 = 30

Answer 1

2x(1)+4x(2)+6x(3) = 18

2x+8x+18x = 18 (sacas mitad)

x+4x+9x = 9

14x = 9

x = 9/14

4x(1)+5x(2)+6x(3) = 24

4x+10x+18x = 24 (sacas mitad)

2x+5x+9x = 12

16x = 12 (sacas cuarta)

4x = 3

x = 3/4

2x(1)+7x(2)+12x(3) = 30

2x+14x+36x = 30 (sacas mitad)

x+7x+18x = 15

26x = 15

x = 15/26
