Question

Solve for f.
2 +1.25f = 10 – 2.75f
f =

Answer 1

2

Explanation:

Answer 2

f = 2

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
