2 Jawaban

  • 3/4x+9/4+1/2x-1/2= 5/4x + 7/4

    maap kalo salah
  • [tex] \frac{3}{4} x + \frac{9}{4} + \frac{1}{2} x - \frac{1}{2} = 0[/tex]

    [tex] \frac{3}{4} x + \frac{1}{2} x + \frac{9}{4} - \frac{1}{2} = \frac{3}{4} x + \frac{2}{4} x + \frac{9}{4} - \frac{2}{4} = \frac{5}{4} x + \frac{7}{4} [/tex]

    [tex] \frac{5}{4} x + \frac{7}{4} = 0
    \\ \frac{5}{4} x = 0 - \frac{7}{4} \\ \frac{5}{4} x = - \frac{7}{4} \\ \\ x = - \frac{7}{4} \times \frac{4}{5} \\ x = - \frac{7}{5} [/tex]

    sorry kalo salah
    dibantu brainliest asnwernya ya thx
