to solve this equation
-15+-3x=10
first combine the x's so to get -3x to the other side add 3x to each side
-15+-3x=10
+3x=+3x
-------------------
you then get
-15= 13x
next you need to get x alone to solve so you have to divide each side by 13
-15/13= x
next check to see if you can simplify the fraction...in this case you can not simplify, so your answer is
x= -15/13
