n=3/13
1) Simplify the right side first. -1/9 = 8/9 - 13n/3
2) Switch the sides so n is on the right (optional): 8/9-13n/3 = -1/9
3) Move all terms not containing n to the right of the equation. Do this by subtracting subtracting. -1/9 - 8/9 = -1
4) Multiply both sides of the equation by 3 to isolate the variable "n".
(3)-13n/3 = -1(3). The new equation is -13n = -1.
5) Divide each term by -13 and simplify. The final answer is n=3/13
