Answer:
x = - 6
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable (x). Divide -15 from both sides
(-15x)/-15 = (90)/-15
x = 90/(-15)
Divide.
x = 90/-15
x = -6
*Remember that when you divide a negative number and a positive number, the result will be a negative answer.
-6 is your answer
