Respuesta:
[tex]5x = 8x - 15 \\ 5x - 8x = - 15 \\ - 3x = - 15 \\ x = - 15 \div 3 \\ x = - 5[/tex]
25=25
Explicacion:
5x=8x−15
1 Haz que x=5x=5.
5\times 5=8\times 5-15
5×5=8×5−15
2 Simplifica 5\times 55×5 a 2525.
25=8\times 5-15
25=8×5−15
3 Simplifica 8\times 58×5 a 4040.
25=40-15
25=40−15
4 Simplifica 40-1540−15 a 2525.
