Question 159883
13x-4 + 9x= 15x + 17 how do you solve this problem?
--------------------
What you wrote is not a problem, it's an expression.
--------------------------
It depends on what you mean by solve.  Solve for x?  
---------------
Assuming you want to solve for x:
13x-4 + 9x= 15x + 17
Collect terms.
22x - 4 = 15x + 17
7x - 4 = 17
7x = 21
x = 3
