Answer:
d
Step-by-step explanation:
rearrange it like an equation.
take everything else out of the middle apart from x.
make sure that what you do to the middle you do to both sides
3x : 2 = 15
3x = 15 * 2
3x = 30
x = 30 : 3
x = 10
--------------------------------
3(10) :2 = 15

Since you know that DA and DC are equal in length, you can say 2x-3=x+2, when you add 3 to both sides, it becomes 2x=x+5, subtract x from both sides, and you find that x=5
