Question

Which equations are related equations to 13 + x = 29?

Answer 1

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.

Answer 2

Answer:

$13=29-x$

$x=29-13$

Step-by-step explanation:

Given equation is $13 + x = 29$

Solve the given equation for x, subtract 13 from both sides

$x=16$

Now we solve each equation given for x

$29 + 13 = x$, x=42

$13=29-x$, subtract 29 from both sides

$-16=-x$ divide both sides by -1

x=16

$x=29-13$, x= 16

$13-x=29$ subtract 13 from both sides

$-x=16$ divide both sides by -1

x=-16

Option B  and C gives the same solution x=16
