Question

ecuaciones, respuesta con procedimiento.

1) 1+8x=-16x+31
2)9+9x=17+5x
3)60x-1=3(1+12x)
4) (x-15)=3(x-19)
5) 3(12-x)-4x=2(11-x)+9x

Answer 1

Hola,

1) 1 +8x = -16x + 31
16x + 8x = 31 - 1
24x = 30
x = 30/24
x = 1,25

2) 9 + 9x = 17 + 5x
9x - 5x = 17 - 9
4x = 8
x = 8/4
x = 2

3) 60x - 1 = 3(1 + 12x)
60x - 1 = 3 + 36x
60x - 36x = 3 + 1
24x = 4
x = 4/24
x = 2/12

4) x - 15 = 3x - 57
3x - x = 57 - 15
2x = 42
x = 42/2
x = 12

5) 3(12 - x) - 4x = 2(11 - x) + 9x
36 - 3x - 4x = 22 - 2x + 9x
7x + 7x = 36 - 22
14x = 14
x = 14/14
x = 1
