Final answer:
Equations B: -76x+76=-76x+76 and C: 76x + 76 = 76x +76 both have infinitely many solutions as they can be simplified to 0 = 0. Equation A: 76x+ 76 = -76x+76 does not have infinitely many solutions because it simplifies to a non-trivial statement.
Explanation:
The question relates to determining which equations have infinitely many solutions. An equation has infinitely many solutions if it can be simplified to a trivial truth, such as a statement where the same value or expression is on both sides of the equals sign.
A: 76x+ 76 = -76x+76 does not have infinitely many solutions because simplifying it gives 76x + 76x = 0, indicating that x can have only one specific value to satisfy the equation.
B: -76x+76=-76x+76 does have infinitely many solutions. Simplifying this gives 0 = 0, a trivial truth regardless of the value of x.
C: 76x + 76 = 76x +76 does have infinitely many solutions. Simplifying leads to 0 = 0, which is always true for any value of x.
D: -76x + 76x +76 is not an equation since it is missing an equals sign and therefore we cannot determine if it has solutions without additional information.
Solution B and C are both correct as they can be simplified to statements that are always true, indicating that they have infinitely many solutions.
