Which equations are related equations to 13 + x = 29?Select each correct answer.29 + 13 = x13=29−xx=29−1313−x=29

Solve the given equation:
13 + x = 29
Subtract 13 from both sides:
x = 16

Now look at each choice and solve for x.

A. 29 + 13 = x
x = 42

B. 13 = 29 - x
-16 = -x
x = 16

C. x = 29 - 13
x = 16

D. 13 - x = 29
-x = 16
x = -16

Choices B and C have the same solution as the given equation, so choices B and C are equivalent to the given equation.
