Answer:
x = ∞ infinite solutions or 0
HI = infinite solutions
ID = infinite solutions.
Step-by-step explanation:
Oh okay I got this now!
ID + HI = DH
ID + 2x - 4 = 4x + 10 (subtract 2x on both sides)
ID - 4 = 2x + 10 (add 4 on both sides)
ID = 2x + 14
So now ID + HI = DH
2x + 14 + 2x - 4 = 4x + 10 (simplify)
4x + 10 = 4x + 10 (subtract 10 on both sides)
4x = 4x (minus 4x on both sides)
0 = 0
I would plug in 0 as x.
Hope this helps!
