This is an absolute value equation so there will always be 2 solutions.
|3x+3|=7 and |3x+3|=-7
First:
|3x+3|=7
We can now remove the absolute value lines...
3x+3=7 and we can solve for x.
Subtract 3 from both sides...
3x = 4
Divide by 3...
x = 4/3
Second:
|3x+3|=-7
remove the absolute value lines...
3x+3=-7
Subtract 2 from both sides...
3x = -10
Divide by 3...
x = -10/3
So, our solution set is...
{-10/3, 4/3}
I hope this helps.
Good Luck!
