To find the value of x, we need to isolate x on one side of the equation.
Starting with the equation -3x + 9 = -19, we can subtract 9 from both sides:
-3x + 9 - 9 = -19 - 9
-3x = -28
Next, we can divide both sides by -3 to solve for x:
(-3x)/-3 = -28/-3
x = 28/3
So the value of x is 28/3, which can also be expressed as 9 1/3.
What is the value of x when −3x+9=−19?
-9
9
