En los ejercicios del 1 al 14 resuelva la ecuacion para despejar x

   4) 3x+7=7x+19

var('x')
x
ecuacion1 = 3*x + 7 == 7*x + 19
solve ([ecuacion1],x)
[x == -3]

   6) 3(x+1)+x^2=x^2+18

var('x')
x
ecuacion1 = 3*(x + 1) + x^2 == x^2 + 18
solve ([ecuacion1],x)
[x == 5]

   7) 1/4x=10-x

var('x')
x
ecuacion1 = 1/4*x == 10 - x
solve ([ecuacion1],x)
[x == 8]
