Ответ:
x = 3
Step-by-step explanation:
-3x = -9
You have to do the inverse operation to solve a linear equation. In this case, the operation is multiplication (-3x) and the inverse would be division.
Thus, we would divide both sides by the coefficient (-3)
-3x/-3 = -9/-3
Thus, we isolate the variable x, and the result is
x = 3
Check:
To check our answer, all we have to do is substitute the value of x.
So, we would substitute the equation as
-3(3) = 9
-3 multiplied by 3 is -9, so our answer is correct.
