Question

2x1 +4x2+6x3 = 18 4X1 +5x2 + x3 = 24 3x + x2 - 2x3 = 4​

Answer 1

Explicación 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
