Answer:
x = 5
Step-by-step explanation:
Hello there!
We'll start off my combining or getting rid of/simplifying like terms.
10x -9 = -2x - 69
+2x +2x
12x-9= -69
Now we want to get rid of the 9 so we can have an equal balanced equation
12x -9 = -69
+9 +9
12x = -60
Now isolate the x to solve
12x = -60
12x/12= -60/12
x = -5
Hope this help you and feel free to comment if u have any questions or need further explanation :)
