Question

como se resuelve esto

71+[-5x+(-2x+3)]=25-[-(3x+4)-(4x+3)]

Answer 1

$71+[-5x+(-2x+3)]=25-[-(3x+4)-(4x+3)] \\ \\ 71+[-5x-2x+3]=25-[-3x-4-4x-3] \\ \\ 71+[-7x+3]=25-[-7x-7] \\ \\ 71-7x+3=25+7x+7 \\ \\ 71+3-25-7=7x+7x \\ \\ 42=14x\to \frac{42}{14}=x\to \boxed{x=3}$

Espero que te sirva, salu2!!!!

Answer 2

71-5x-2x+3=25+3x+4+4x+3
71+3-25-4-3=3x+4x+5x+2x
42=14x
x=3
