7(x-2)-6x+1=3-4x
7x-14-6x+1=3-4x
x-14+1=3-4x
x-13=3-4x
x+4x=3+13
5x=16
x=16/5
conprobamos
7(16/5-2)-6(16/5)+1=3-4(16/5)
7×6/5-6(16/5)+1=3-4(16/5)
7×6/5-96/5+1=3-4(16/5)
7×6/5-96/5+1=3-64/5
42/5-96/5+1=3-64/5
42/5-96/5+1= -49/5
-54/5+1= -49/5
-49/5= -49/5
Explicación paso a paso:
espero te sirva la respuesta
7(x - 2) - 6x + 1 = 3 - 4x
7x - 14 - 6x + 1 = 3 - 4x
7x - 6x + 4x = 3 + 14 -1
5x = 16
x = 16/5
x = 3,2
