Question

28 - f =30.5 What is the value of f

Answer 1

-2.5

Explanation:

28 - f = 30.5

-f = 30.5-28

-f=2.5

f=-2.5

Answer 2

`\huge\text{Hey there!}`

`\mathsf{28 - f =30.5}`

`\large\textsf{Or you can say: \textsf{-f + 28 = 30.5}}`

`\rm{SUBTRACT\ 28\ to\ BOTH\ SIDES}`

`\mathsf{-f + 28 - 28 = 30.5 - 28}`

`\rm{CANCEL\ out: 28 - 28\ because\ that\ gives\ you\ 0}`

`\rm{KEEP: 30.5 - 28\ because\ that\ helps\ solve\ for\ your\ f-value}`

`\mathsf{30.5-28=\bf 2.5}`

`\rm{New\ EQUATION: -f = 2.5}`

`\textsf{When we have a variable by itself, it is usually understood as an invisible 1 }`

`\rm{DIVIDE\ -1\ to\ BOTH\ SIDES}`

`\mathsf{(-f)/(-1)=(2.5)/(-1)}`

`\rm{CANCEL\ out: (-1)/(-1)\ because\ that\ gives\ you\ 1}`

`\rm{KEEP: (2.5)/(-1)\ because\ it\ gives\ you\ the\ f-value\ result}`

`\mathsf{f =(2.5)/(-1)}\\\\\large\text{or you can say}\downarrow\\\\\mathsf{2.5/ -1=\bf f}`

`\uparrow\textsf{SIMPLIFY ABOVE AND YOU WILL HAVE YOUR RESULT OF \bf F}\uparrow`

`\boxed{\boxed{\large\text{Amswer: \huge \bf f = -2.5}}}\huge\checkmark`

`\large\text{Good luck on your assignment and enjoy your day!}`
