por favor me ajudem​

Answer 1

Resposta:

)

\frac{x}{2} - \frac{x}{3} = 52x−3x=5

b)

\frac{x}{5} + \frac{x}{4 } = 35x+4x=3

c)

\frac{x}{6} + \frac{x}{4} = - 56x+4x=−5

d)

\frac{x + 1}{3} + \frac{x + 2}{4} = 23x+1+4x+2=2

e)

\frac{x + 1}{3} - \frac{x - 3}{5} = 23x+1−5x−3=2

f)

\frac{2x + 3}{2} - \frac{2x - 5}{3} = 322x+3−32x−5=3
