Question

resuelva 4x+8=3x+1                                                  18x-6+15x=10x+7+7x



20x+9-8x=25-14x+2

Answer 1

4x + 8 = 3x + 1
4x - 3x = 1 - 8
x = -7

18x - 6 + 15x = 10x + 7 + 7x
33x - 6 = 17x + 7
33x - 17x = 7 + 6
16 x =7 13
x = 13/16

20x + 9 - 8x = 25 - 14x + 2
12x + 9 = 27 - 14x
12x + 14x = 27 - 9
2x = 18
x = 9

Answer 2

4x + 8 = 3x + 1 
4x - 3x = 1 - 8
x = - 7
Solución
x = - 7


18x - 6 + 15x = 10x + 7 + 7x
18x + 15x - 6 = 10x + 7x + 7
33x - 6 = 17x + 7
33x - 17x = 7 + 6
16x = 13
x = 13/16
Solución.
x = 13/16



20x + 9 - 8x = 25 - 14x + 2
20x - 8x + 9 = - 14x + 2 + 25
12x + 9 = - 14x + 27
12x + 14x = 27 - 9
26x = 18
x = 18/26
x = 9/13
Solución.
x = 9/13
