ejercicios de ecuacion lineal

Answer 1

·       7x + 6x + 9x – 60 +40 – 25 + 9x = 6x -4x – 6

7x + 6x + 9x – 6z +4x = -6 +60 -40 +25
29x = 39
x = 39 / 29
x = 1.34

·       80 x + 6x -10 = 60x +140 +32

80x + 6x -60x = 140 + 32 +10
26x = 182
x= 182 / 26
x= 7

·       24x -8x +12 – 8 = 6x + 20 +4

24x – 8x -6x = 20 + 4 -12 +8
10 x = 20
x = 20 /10
x=2
