Question

Which of the following equations are equivalent? Select three options. 2 + x = 5 x + 1 = 4 9 + x = 6 x + (negative 4) = 7 Negative 5 + x = negative 2

Answer 1

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.
