Question

Find x

a. 12
b. 20
c. 24
d. 32

Answer 1

a. 12

Explanation:

The two points will be equal to one another. With that in mind the equation will have = in it

x+24=3x

Get rid of alike terms by subtracting x from both sides (x-x) and (3x-x)

24=2x

now divide both sides by 2 (2x/2) and 24/2)

x=12
