Mathematics
1 answer:
Dmitry_Shevchenko [17]3 years ago
7 0

Answer: a

no solution

Step-by-step explanation:

Solve by substitution:

1) Solve x=2y+4 for x:

x=2y+4

2) Substitute 2y+4 for x in 2y=x-6:

2y=x-6

2y=2y+4-6

3) Simplify both sides of the equation:

2y=2y-2

4) Add -2y to both sides of the equation:

2y+-2y=2y-2+-2y

5) Simplify both sides of the equation:

0=-2

Therefore, there are no solutions to the system of equations.

Solve by elimination:

You can't solve this system of equations by elimination

Solve by graphing:

The equations are parallel to each other, therefore they never cross, so, there are no solutions.
