Hola! !!!

Explicación paso a paso:

Ecuacion | Resolver | Comprobar |

5X+4=49 | 5X= 49-4 | 5×9 + 4 = 49 |

| X=45/5 | 45+ 4 =49 |

| X= 9 | 49=49 |

3X+1=31 | 3X=31-1 | 3×10+1=31 |

| X=30/3 | 30 + 1=31 |

| X=10 | 31 = 31 |

7X+1=36 | 7X=36-1 | 7×5+1=36 |

| X= 35/7 | 35+ 1=36 |

| X=5 | 36=36 |

9X+1=91 | 9X=91-1 | 9×10+1=91 |

| X = 90/9 | 90 + 1=91 |

| X=10 | 91=91 |

2X+9=13 | 2X=13-9 | 2×2+9 = 13 |

| X = 4/2 | 4 + 9 =13 |

| X= 2 | 13 =13 |

8X+8=64 | 8X=64-8 | 8×7+8=64 |

| X= 56/8 | 56+8=64 |

| X= 7 | 64=64 |

3X+3=27 | 3X= 27-3 | 3×8+3=27 |

| X = 24/3 | 24+3=27 |

| X = 8 | 27=27 |

3X+9=30 | 3X=30-9 | 3×7+9=30 |

| X= 21/3 | 21 + 9 =30 |

| X=7 | 30 =30 |

1X+3=8 | 1X=8-3 | 1×5+3 = 8 |

| X= 5/1 | 5 + 3= 8 |

| X= 5 | 8= 8 |

4X+2=26 | 4X=26-2 | 4×6+2=26 |

| X =24/4 | 24+2=26 |

| X= 6 | 26=26 |

Espero te sirva.

Saludos !!! :)
