Answer:
[tex]\boxed{ c=\dfrac{23}{2} }[/tex]
Step-by-step explanation:
[tex]\dfrac{a}{b} - d = \dfrac{2c}{b}[/tex]
Once [tex]a =3 , b = 4, d = -5[/tex]
[tex]\dfrac{3}{4} - (-5) = \dfrac{2c}{4}[/tex]
[tex]\dfrac{3}{4} +5 = \dfrac{c}{2}[/tex]
[tex]\dfrac{3}{4} +\dfrac{20}{4} = \dfrac{c}{2}[/tex]
[tex]\dfrac{23}{4} = \dfrac{c}{2}[/tex]
[tex]4c = 46[/tex]
[tex]\boxed{ c=\dfrac{23}{2} }[/tex]
