Step-by-step explanation:
They are congruent
D is your answer. Hope this helped!
We want to find x in times of y and z, so we want to have only 1 x on the LHS of equation, so
3x-7y=z /+7z (add 7z both sides)
3x=z+7z /:3 (divide 3 both sides)
- its the result.

No, because 4/6 would round out to 1/3 whereas 4/8 would round down to 1/2
