If 7 less than 4 times a number is 2 more than 3 times that number, what is the number?

Identify the bottom line. the value of the number = ?
Assess your options. You could start guessing and trying, but the more effective method will be to use a method. In this type of problem, it is most straightforward to translate the statement from English to math and then solve.
Attack the problem.
The statement translates to: 4x – 7 = 3x + 2
The bottom line is: what is x?
When we solve for x we get x = 9.
Loop back. Verify that you solved for the bottom line.
The correct answer is 9. Grid it in.
Level = Medium
