Question

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

Answer 1

Respuesta:

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

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

71 + [-7x + 3] = 25 + 3x + 4 + 4x + 3

71 - 7x + 3 = 25 + 3x + 4 + 4x + 3

-7x - 3x - 4x = 25 + 4 + 3 - 71 - 3

-14x = -42

x = -42/-14

x = 3
