Question

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

Answer 1

Respuesta:

X=21/5

Explicación paso a paso:

71+(-3x + 3) = 25-(-7x - 7)

74 - 3x = 32 + 7x

-3x - 7x = 32 - 74

-10x = -42

x = 42/10

x= 21/5

Verificación

71 + (-3(21/5) + 3) = 25 - (-7(21/5) - 7)

71 + (-63/5 + 3) = 25 - (-147/5 - 7)

71 - 48/5 = 25 + 182/5

307/5 = 307/5
