Question 168303
{{{7>=3x-2<19}}}add 2 to each term
{{{9>=3x<21}}}divide each term by 3
{{{3>=x>7}}} which states that x is greater than or equal to 3 and less than 7

I cant get my numberline to work but you should have 3 with a solid circle and a solid line moving to 7 with a hollow circle at 7 because 7 is not inclusive.

interval notation [3,7)
