Question 735881: [8x+9]+3=8
its the absolute value of 8x+9 but don't have those buttons on my keyboard.

Yes you do have "those buttons" (that key) on your keyboard.

Hold the shift key down and press the key that looks like this

. You'll find it just above the ENTER and just below the
Backspace key.

|8x+9| + 3 = 8

Add -3 to both sides

    |8x+9| = 5

Since both |5|=5 and |-5|=5 this breaks into two equations:

8x+9 = 5   and   8x+9 = -5 
  8x = -4          8x = -14
   x = -4%2F8           x = -14%2F8
   x = -1%2F2           x = -7%2F4

Those are the two solutiuons.
