the problem is 5f+7 less than or equal to 22. can anyone please work this out for me and check it for me? and what i mean by checking it is like when you get the answer you check it and make sure its write.
5f + 7 ≤ 22
An inequality is treated just like an equation, except that multiplying/dividing by a negative value reverses the carat (< to >).
Subtract 7 from both sides, then divide both sides by 5.
