Question

I really need help
If AD = 12 and AC = 4y-36, find the value of y

Answer 1

y = 15

Explanation:

Consider that the attached screenshot is the figure given in the problem. Also consider that DC = 12, due to the fact that AD = 12, and there is a midpoint at point D.

AD + DC = AC

12 + 12 = 4y - 36

24 = 4y - 36

+ 36 + 36

60 = 4y

60/4 = 4y/4

y = 15

Answer 2

y=12

Explanation:

in that case, then 12 = 4y -36

12 =4y -36

12+36=4y

48=4y

48/4=y

12=y

answer :y=12
