+-9+%3C+4x+-1+%3C+15+
So we solve for x, but, we keep x in the middle.
+-9+%2B+1+%3C+4x+-1+%2B+1+%3C+15+%2B+1+
This is what one gets when the 1 is taken out notice that the 1 is added to both sides.
+8+%3C+4x+%3C+16+
Then finally we have divide the 4 out, which we do to both sides.
+8%2F4+%3C+4x%2F4+%3C+16%2F4+
Which leaves us with the final answer.
+2+%3C+x+%3C+4+
