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 following equations are equivalent:

2 + x = 5

x + 1 = 4

Negative 5 + x = negative 2

This is because, in each equation, x is the same variable, and it has the same value on both sides of the equation.

In the first equation, x is equal to 3.

In the second equation, x is equal to 3

In the third equation, x is equal to -3

Note that the equation 9 + x = 6 and x + (negative 4) = 7 are not equivalent as these equations have different values for x.
