Question 657328
In equations, there are 2 "sides" on either side of the = sign.  In your problem, there are 3 "sides", so we add, subtract, multiply, divide all 3 sides:
<br>
25 < 5x - 15 < 45 
40 < 5x   < 85   (added 15 to all 3 "sides")
8 < x < 17  (divided all 3 "sides" by 5)
<br>
If you have to graph this, it's a number line with open circles at 8 and 17 with shading in the middle. 0--------0
