Solve. 3x + 3 = 21 (1 point) Responses x = 5 x = 5 x = 6 x = 6 x = 18 x = 18 x = 36 x = 36
To solve the equation 3x + 3 = 21, we need to isolate x on one side of the equation.
Starting with the given equation:
3x + 3 = 21
We can begin solving by subtracting 3 from both sides of the equation:
3x + 3 - 3 = 21 - 3
3x = 18
Next, divide both sides of the equation by 3 to solve for x:
3x/3 = 18/3
x = 6
So, the solution to the equation is x = 6.
To solve the equation 3x + 3 = 21, we can follow these steps:
Step 1: Subtract 3 from both sides of the equation:
3x + 3 - 3 = 21 - 3
3x = 18
Step 2: Divide both sides of the equation by 3 to isolate x:
(3x) / 3 = 18 / 3
x = 6
Therefore, the solution to the equation is x = 6.
To solve the equation 3x + 3 = 21, we need to isolate the variable x by performing the necessary steps to move the other terms to the other side of the equation.
Step 1: Start by subtracting 3 from both sides of the equation to eliminate the constant term on the left side:
3x + 3 - 3 = 21 - 3
This simplifies to:
3x = 18
Step 2: Next, divide both sides of the equation by 3 to isolate the variable x:
3x/3 = 18/3
This simplifies to:
x = 6
Therefore, the solution to the equation 3x + 3 = 21 is x = 6.
