Match each equation on the left to its solution on the right.
Some answer choices on the right will be used more than once.

[tex]\[
\begin{array}{l}
1. -4 + 6x = 2(3x - 3) \\
2. 3(5x + 2) = 5(3x - 4) \\
3. 8 - 2x = 2x - 8 \\
4. -3x + 3 = -3(1 + x)
\end{array}
\][/tex]

[tex]\[
\begin{array}{l}
\text{A. } x = 4 \\
\text{B. } x = \text{all real numbers} \\
\text{C. } \text{no solution}
\end{array}
\][/tex]



Answer :

Let's analyze each equation one by one and match them to their solutions:

1. Equation: [tex]\(-4 + 6x = 2(3x - 3)\)[/tex]

Simplify the right-hand side:
[tex]\[ 2(3x - 3) = 6x - 6 \][/tex]

So the equation becomes:
[tex]\[ -4 + 6x = 6x - 6 \][/tex]

Subtract [tex]\(6x\)[/tex] from both sides:
[tex]\[ -4 = -6 \][/tex]

This statement is false. Therefore, this equation has no solution.

2. Equation: [tex]\(3(5x + 2) = 5(3x - 4)\)[/tex]

Simplify both sides:
[tex]\[ 3(5x + 2) = 15x + 6 \][/tex]
[tex]\[ 5(3x - 4) = 15x - 20 \][/tex]

So the equation becomes:
[tex]\[ 15x + 6 = 15x - 20 \][/tex]

Subtract [tex]\(15x\)[/tex] from both sides:
[tex]\[ 6 = -20 \][/tex]

This statement is also false. Therefore, this equation also has no solution.

3. Equation: [tex]\(8 - 2x = 2x - 8\)[/tex]

Move all terms involving [tex]\(x\)[/tex] to one side:
[tex]\[ 8 - 2x - 2x = -8 \][/tex]
[tex]\[ 8 - 4x = -8 \][/tex]

Add 8 to both sides:
[tex]\[ 8 + 8 - 4x = 0 \][/tex]
[tex]\[ 16 - 4x = 0 \][/tex]

Move the constant term to the other side:
[tex]\[ -4x = -16 \][/tex]

Divide both sides by [tex]\(-4\)[/tex]:
[tex]\[ x = 4 \][/tex]

Therefore, this equation has the solution [tex]\(x = 4\)[/tex].

4. Equation: [tex]\(-3x + 3 = -3(1 + x)\)[/tex]

Expand the right-hand side:
[tex]\[ -3x + 3 = -3 - 3x \][/tex]

Move all terms involving [tex]\(x\)[/tex] to one side:
[tex]\[ -3x + 3x + 3 = -3 \][/tex]
[tex]\[ 3 = -3 \][/tex]

This statement is false. Therefore, this equation has no solution.

So, the final matching is:
- [tex]\(-4 + 6x = 2(3x - 3)\)[/tex] matches no solution
- [tex]\(3(5x + 2) = 5(3x - 4)\)[/tex] matches no solution
- [tex]\(8 - 2x = 2x - 8\)[/tex] matches x = 4
- [tex]\(-3x + 3 = -3(1 + x)\)[/tex] matches no solution
