To solve for x, we want to isolate x on one side of the equation.
Given the equation: 3x + 0.2 = x + 8
We can start by subtracting x from both sides:
3x - x + 0.2 = x - x + 8
2x + 0.2 = 8
Next, we can subtract 0.2 from both sides:
2x + 0.2 - 0.2 = 8 - 0.2
2x = 7.8
Finally, divide both sides by 2:
2x/2 = 7.8/2
x = 3.9
Therefore, the solution for x is 3.9. None of the answer choices provided match the solution, so none of the options A, B, C, or D is correct.

To solve for x, we want to isolate x on one side of the equation.
Given the equation: 3x + 2 = x + 8
Subtracting x from both sides to get all the x terms on one side:
3x - x + 2 = x - x + 8
2x + 2 = 8
Subtracting 2 from both sides:
2x + 2 - 2 = 8 - 2
2x = 6
Dividing both sides by 2:
2x / 2 = 6 / 2
x = 3
Therefore, the solution for x is 3. The correct answer is C. 3
To solve for x, we can start by isolating the terms with x on one side of the equation.
Given equation: 3x + 0.2 = x + 8
First, we can subtract x from both sides to get rid of the x term on the right side:
3x - x + 0.2 = x - x + 8
This simplifies to:
2x + 0.2 = 8
Next, we can move the constant term (0.2) to the other side by subtracting 0.2 from both sides:
2x + 0.2 - 0.2 = 8 - 0.2
Simplifying further:
2x = 7.8
Finally, to solve for x, we divide both sides by 2:
2x/2 = 7.8/2
This gives us:
x = 3.9
So the solution to the equation is x = 3.9.
Therefore, the correct answer is:
О с. 3
To solve for x, we need to isolate the variable x on one side of the equation. Let's solve the given equation step by step:
3x + 0.2 = x + 8
First, let's simplify the equation by combining like terms on each side:
3x - x = 8 - 0.2
Simplifying further, we get:
2x = 7.8
Next, let's isolate x by dividing both sides of the equation by 2:
(2x) / 2 = 7.8 / 2
x = 3.9
Therefore, the value of x that satisfies the equation is x = 3.9.
However, the answer choices provided are all whole numbers. If you are looking for the nearest whole number answer, you can round the value of x.
The closest whole number to x = 3.9 is 4.
So, the choice closest to the solution is:
