Question

6e - 7f = 8g + h, solve for f

Answer 1

Isolate the f. Note the equal sign. What you do to one side, you do to the other.

First, subtract 6e from both sides

6e (-6e) - 7f = 8g + h (-6e)

-7f = 8g + h - 6e

Divide -7 from both sides

(-7f)/-7 = (8g + h - 6e)/-7

f = -8/7g + h/-7 + 6/7e

f = -8/7g + h/-7 + 6/7e is your answer

hope this helps
