Answer:
x= -2
Step-by-step explanation:
First, distribute the 3 into the parenthesis.
(-3)x+ (-3)5= -9
Then, multiply.
-3x-15= -9 *The negative makes it into becoming subtraction.
Now, add 15 to both sides since that's the opposite of subtraction.
-3x-15= -9
+15 +15
Then, divide by 3 to both sides to isolate the variable.
-3x= 6
-3 -3
x= -2
