¡Hola!
Vamos a resolver las ecuaciones de primer grado.
12x + 20 - 8 = 20 + 6
12x + 12 = 26
12x = 26 - 12
12x = 14
Rpt Fracción:
x = 14/12 = 7/6
Rpt Decimal:
x = 1.1666666667
x/7 + 10 = 15 + 2
x/7 + 10 = 17
x/7 = 17 - 10
x/7 = 7
x = 7×7
x = 49
Rpt:
" Life is not a problem to be solved but a reality to be experienced! "
