Question

I don’t know it tried solving it but couldn’t find it

Answer 1

f = 9

Explanation:

8f - 25 = 47

Add 25 to both sides.

8f - 25 + 25 = 47 + 25

On the left side, -25 + 25 = 0, so the -25 is eliminated.

On the right side, we add 47 + 25 = 72

8f = 72

Now we divide both sides by 8.

`(8f)/(8) = (72)/(8)`

8f divided by 8 is just f. 72 divided by 8 is 9.

f = 9

Answer 2

8f - 25 = 47. Add 25 to both sides.

8f = 72. Divide each side by 8.

f = 9.
