The three equivalent equations are:
2 + x = 5
x + 1 = 49
-5 + x = -2
Step-by-step explanation:
Subtracting 2 from both sides of the equation 2 + x = 5 gives x = 3, which is the solution to the equation.
Subtracting 1 from both sides of the equation x + 1 = 49 gives x = 48, which is the solution to the equation.
Adding 5 to both sides of the equation -5 + x = -2 gives x = 3, which is the solution to the equation.
