f is an integer. Write down the largest value of f that satisfies f – 15 > 35 + 5f

f-15 > 35 + 5f    subtract  f from both sides of the equation

-15 > 35 + 4f     Subtract 35 from both sides

-50 > 4f              Divede both sides by 4

-12.5 > f    or   f < -12.5        so the largest integer that satifies this is -13
