Which is the best interpretation of the solution set for the compound inequality?

3(2x + 1) > 21 or 4x + 3 < 3x + 7

no solution
3 < x < 4
x < 3 or x > 4
all real numbers

  all real numbers

Step-by-step explanation:

Here is the solution to the first inequality:

  3(2x +1) > 21 . . . . . . given

  6x +3 > 21 . . . . . . . . eliminate parentheses

  6x > 18 . . . . . . . . . . .subtract 3

  x > 3 . . . . . . . . . . . . divide by 6

This is all numbers to the right of 3 on the number line.

The solution to the second inequality is ...

  4x +3 < 3x + 7 . . . . given

  x < 4 . . . . . . . . . . . . subtract 3x+3

This is all numbers to the left of 4 on the number line.

The conjunction in the system of inequalities is "or", so we are looking for values of x that will satisfy at least one of the conditions. Any value of x will satisfy one or the other or both of these inequalities. The solution is all real numbers.
