What can you do to isolate a variable in an inequality?
No solution.
Inequalities can be solved in the same way as equations, by performing inverse operations on both sides until the variable is isolated. The only difference is that when we divide or multiply by a negative number, we must reverse the inequality sign.
Distribute 3
LHS-9>RHS-9
LHS-15f>RHS-15f
Here, we have produced a false statement as 0 is not greater than itself. This tells us that there is no solution to the inequality as no value of f can make the statement true.
