Use the substitution method from using the mutiple choices.

The two numbers must equal to each other.

x= 2

(2+50)/2= 13(2)

add first then divide

(52)/2= 13(2)

26= 26

Answer: x= 2

(x+50)/2 = 13x

First multiply both sides by 2 to remove the fraction:

x +50 = 26x

Subtract 1x from each side:

50 = 25x

Divide both sides by 25:

x = 50/25

x = 2
