7. | 3x - 2 | = 8 and | x + 1 | = 1
What value of x satisfies both equations above?

If |x+1| = 1,
x+1 is either 1 or -1, so
x = 0 or -2
Does either of those values satisfy the other equation?

Steve is it no solution?

Did you try the values?
|3x-2| = |3*0-2| = |-2| = 2
|3x-2| = |3(-2)-2| = |-6-2| = |-8| = 8
This is the solution.
