|3+9c| -19 = -1
im supposed to solve and write the solution set.
|3+9c| -19 = -1
i added 19 to both sides
|3+9c|= 18
i subtracted 3 from both sides
9c= 15
i divided both sides by 9 and reduced
so now i have c= 5/3
then i solved for the positive case:
|3+9c| -19 = 1
added 19 on both sides
|3+9c| = 20
subtracted 3 from both sides
9c = 17
divided both sides by 9, so now i have
c= 17/9
so the solution set should be written as: {17/9, 5/3} right?
but the website im doing my work on says this is incorrect and i have no idea what i did wrong?
