Answer:
(- 3, - 6 ) , (1, 2 )
Step-by-step explanation:
2y = 4x ( divide both sides by 2 )
y = 2x → (1)
x² + y = 3 → (2)
Substitute y = 2x into (2)
x² + 2x = 3 ( subtract 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Substitute theses values into (2) for corresponding values of y
x = - 3 : y = 2(- 3) = - 6 ⇒ (- 3, - 6 )
x = 1 : y = 2(1) = 2 ⇒ (1, 2 )

Step-by-step explanation:
The expression of the description when written as follows;
'I am a 6-digit number one of my 4s is worth 400,000. The other 5 is worth 1/100 as much. My 5 is worth 5 (10s). y 8 is worth 800. My 2 is' worth 2. My other digit is a 0 what number am I, we have;
The number of digits in the number = 6
The position of the number 4 = 100,000s, we have;
4xx,xxx
The position of the number 5 is in the 10s position, we have;
4xx,x5x
The other 5 = 50100 = 0.5
Therefore, we have;
4xx,x5x.5
The position of the 8 is the 100s, to give;
4xx,85x.5
The number 2 is in the unit position, therefore, we have;
405,852
Mars<span> and Earth orbit the </span>sun<span> at different speeds: Earth has an inside track and gets around the sun more quickly. Plus, both have elliptical orbits, rather than perfect circles. So the distance to Mars from Earth is constantly changing. In theory, the closest the planets could come together would be when Mars is at its </span>closest point<span> to the sun (</span>perihelion) and Earth is at itsfarthest point<span> (</span>aphelion<span>). In that situation, the planets would be 33.9 million miles (54.6 million kilometers) from each other. But that has never happened in recorded history. The closest known approach was 34.8 million miles (56 million km) in 2003 ....... :D!
