1. add the numbers → 25-4x = 15-3x+10-x
↓
25-4x = 25-3x-x
2. collect like terms 25-4x = 25-3x-x
↓
25-4x = 25-4x
3. the statement is true because if you subtract 25 from both side you are left with
-4x = -4x
then you would divide both sides by -4 to get
x=x which has infinitely many solutions and is rational/true

Answer:
Ty = √k * Tx
The orbital period of Y has to be be multiplied by √k . or . k∧1/2
Step-by-step explanation:
The general equation:
T² = A³
is for the case of planet X
Tₓ² = Aₓ³
In the case of planet Y
Ty² = k * Aₓ³ . and Aₓ³ = Tₓ²
By substitution:
Ty² = k *Tₓ²
Ty = √k * Tx
