The two lines in this system of equations are parallel
Step-by-step explanation:
Let us revise the relation between 2 lines
- If the system of linear equations has one solution, then the two line are intersected
- If the system of linear equations has no solution, then the two line are parallel
- If the system of linear equations has many solutions, then the two line are coincide (over each other)
∵ The system of equation is
3x - 6y = -12 ⇒ (1)
x - 2y = 10 ⇒ (2)
To solve the system using the substitution method, find x in terms of y in equation (2)
∵ x - 2y = 10
- Add 2y to both sides
∴ x = 2y + 10 ⇒ (3)
Substitute x in equation (1) by equation (3)
∵ 3(2y + 10) - 6y = -12
- Simplify the left hand side
∴ 6y + 30 - 6y = -12
- Add like terms in the left hand side
∴ 30 = -12
∴ The left hand side ≠ the right hand side
∴ There is no solution for the system of equations
∴ The system of equations represents two parallel lines

Answer:
I think question is incomplete . So I can't give answer.
25 tens = 2 Hundreds 5 ones
Answer:
That would be 1/57.1
Step-by-step explanation:
It would be the fraction 1 over 57.1 because miles comes before hours in the lable so it would be
1 / 57.1
Answer:
=x
Step-by-step explanation:
1. Subtract 7 from both sides.
y−7=2x
2. Divide both sides by 2.
=x
