[tex]\\ \sf\longmapsto -4d-5=-1[/tex]

  • Cancel - from both sides

[tex]\\ \sf\longmapsto -(4d+5)=-(1)[/tex]

[tex]\\ \sf\longmapsto 4d+5=1[/tex]

[tex]\\ \sf\longmapsto 4d=1-5[/tex]

[tex]\\ \sf\longmapsto 4d=-4[/tex]

[tex]\\ \sf\longmapsto d=\dfrac{-4}{4}[/tex]

[tex]\\ \sf\longmapsto d=-1[/tex]
