Answer:
f = 2
Step-by-step explanation:
To get f on one side of the equal sign and the constant terms on the other side, you can add (2.75f-2) to both sides of the equation:
4f = 8
Dividing by the coefficient of f gives the desired result.
f = 2

Check
2 +1.25(2) = 10 -2.75(2)
2 +2.50 = 10 -5.50
4.50 = 4.50 . . . . the answer checks OK
