Question

If you add 13 to four times a certain number, the sum is less than 265. Let x represent the number. Write an inequality that can be solved to find the value of x.

Answer 1

Well, if that is transformed into an expression, it would be 4x+13<265.
To solve it, just transpose 13 to the other side. 4x<265-13
and divide both sides b four to know the value of x. :)
