Which of the following equations have infinitely many solutions? Choose all answers that apply:

A. [tex]76x + 76 = 76x + 76[/tex]

B. [tex]76x + 76 = -76x + 76[/tex]

C. [tex]-76x + 76 = 76x + 76[/tex]

D. [tex]-76x + 76 = -76x + 76[/tex]

Answer :

To determine which equations have infinitely many solutions, we need to analyze each equation to see when both sides are exactly the same for any value of [tex]\(x\)[/tex].

Let's examine each equation one by one:

Equation A: [tex]\(76x + 76 = 76x + 76\)[/tex]

- Both sides of the equation are exactly the same.
- This means that for any value of [tex]\(x\)[/tex], the equation will hold true since each side is identical.
- Hence, this equation has infinitely many solutions.

Equation B: [tex]\(76x + 76 = -76x + 76\)[/tex]

- If we simplify both sides, we get:
- [tex]\(76x + 76 = -76x + 76\)[/tex]
- Bring like terms involving [tex]\(x\)[/tex] together: [tex]\(76x + 76x = 0\)[/tex]
- Simplifying gives [tex]\(152x = 0\)[/tex]
- Solving for [tex]\(x\)[/tex], we find [tex]\(x = 0\)[/tex].
- This equation has exactly one solution, which is [tex]\(x = 0\)[/tex].

Equation C: [tex]\(-76x + 76 = 76x + 76\)[/tex]

- Simplifying both sides, we get:
- [tex]\(-76x + 76 = 76x + 76\)[/tex]
- Bring like terms involving [tex]\(x\)[/tex] together: [tex]\(-76x - 76x = 0\)[/tex]
- Simplifying gives [tex]\(-152x = 0\)[/tex]
- Solving for [tex]\(x\)[/tex], we find [tex]\(x = 0\)[/tex].
- This equation has exactly one solution, which is [tex]\(x = 0\)[/tex].

Equation D: [tex]\(-76x + 76 = -76x + 76\)[/tex]

- Both sides of the equation are exactly the same.
- This implies that for any value of [tex]\(x\)[/tex], the equation will hold true since each side is identical.
- Therefore, this equation has infinitely many solutions.

Conclusion:

Equations A and D have infinitely many solutions because they are true for any value of [tex]\(x\)[/tex].
