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

The inequality: 4x + 13 < 265
thus, 4x < 265 - 13
x < 63

Answer 2

4x + 13 < 265
4x < 252

therefore,
x < 63

Answer 3

Let the number we need to find, be x.
So, given that:
\[13+4x <265\] is the inequality which can be solved to find the value of x.
In either case,
\[13+4x<265\]
\[4x<265-13\]
\[4x<252\]
\[x<252/4\]

\[x<63\] Well that is your final answer for x-value :)
