What is the value of x when −3x+9=−19? (1 point) Responses -9 -9 9 9 323 3 and 2 thirds −323
The value of x when −3x+9=−19 is 9.
To find the value of x, we can solve the equation −3x + 9 = −19 step by step.
Step 1: Let's start by isolating the variable term. We can do this by subtracting 9 from both sides of the equation:
−3x + 9 - 9 = -19 - 9
This simplifies to:
−3x = -28
Step 2: Next, we need to get rid of the coefficient -3 in front of x. To do this, we divide both sides of the equation by -3:
(-3x) / -3 = -28 / -3
This simplifies to:
x = 28/3
So, the value of x when −3x + 9 = −19 is 28/3.
To find the value of x when −3x+9=−19, we can use algebraic methods to isolate x.
Step 1: Let's start by subtracting 9 from both sides of the equation to get rid of the constant term on the left side:
-3x + 9 - 9 = -19 - 9
-3x = -28
Step 2: Next, we want to isolate x, so we divide both sides of the equation by -3 (the coefficient of x):
(-3x)/-3 = -28/-3
x = 28/3
Therefore, the value of x is 28/3, which can also be written as 9 and 1/3.
