Question

no puedo resolver este ejercicio 4x+1+2(5+x)=x+71

Answer 1

simple:

4x+1+2(5+x)=x+71
4x+1+10+2x=x+71
6x+11=x+71
6x-x=71-11
5x=60
x=60/5
x=12 =>respuesta

verificamos:

4x+1+2(5+x)=x+71
4(12)+1+2(5+12)=12+71
48+1+2(17)=83
49+34=83
83=83

igualdad verdadera

espero ayude

Answer 2

4x +1 +2(5 +x ) = x +71
4x +1 +10+2x = x+71
6x +11 = x+71
6x -x = 71-11
5x = 60
x = 60/5
x = 12

comprobacion
4*12+1 +2(5+12) =12+71
48+1+34 = 83
83  =83
