Solve for x to determine if the equation has one, none or infinite solutions.

Question

5 (2x + 2) - 4 = 2x + 6

answers:

The equation has one solution: x = 0

The equation has no solutions

The equation has infinite solutions.

The equation has one solution: x = 1

Answer 1

Let's solve the equation step by step:

The given equation is:

\[ 5(2x + 2) - 4 = 2x + 6 \]

1. Distribute the 5 on the left side:

\[ 10x + 10 - 4 = 2x + 6 \] \[ 10x + 6 = 2x + 6 \]

2. Now, subtract \(2x\) from both sides:

\[ 10x - 2x + 6 = 6 \] \[ 8x + 6 = 6 \]

3. Next, subtract 6 from both sides:

\[ 8x = 0 \]

4. Finally, divide by 8:

\[ x = 0 \]

Now, let's determine the type of solution:

Since we found one specific solution \(x = 0\), the equation has one solution.

Thus, the answer is:

The equation has one solution: x = 0.

Answer 3

Let's go through the problem again step by step to ensure the solution is correct.

Starting with the original equation:

\[ 5(2x + 2) - 4 = 2x + 6 \]

1. Distribute the \(5\) on the left side:

\[ 5 \cdot 2x + 5 \cdot 2 - 4 = 2x + 6 \] This simplifies to: \[ 10x + 10 - 4 = 2x + 6 \] So now we have: \[ 10x + 6 = 2x + 6 \]

2. Next, subtract \(2x\) from both sides:

\[ 10x - 2x + 6 = 6 \] This simplifies to: \[ 8x + 6 = 6 \]

3. Now, subtract \(6\) from both sides:

\[ 8x + 6 - 6 = 6 - 6 \] This gives us: \[ 8x = 0 \]

4. Finally, divide both sides by \(8\):

\[ x = 0 \]

Now, let's determine if the equation has one solution, no solutions, or infinite solutions:

Since we obtained a specific solution of \(x = 0\), the equation indeed has one solution.

Therefore, the conclusion is correct:

The equation has one solution: x = 0.
