Answer:
x = 3
Step-by-step explanation:
-6x - 20 = -2x + 4 (1 - 3x)
Distributive property
-6x - 20 = -2x + 4 - 12x
Combine like terms
-6x - 20 = -14x + 4
Add 14x to both sides
-6x - 20 + 14x = -14x + 4 + 14x
Simplifying
8x - 20 = 4
Add 20 to both sides
8x = 24
Divide both sides by 8
x = 3

Answer: Yes
Step-by-step explanation:
First multiply the first equation by three to get 3x+12y=69
Then subtract 12y from both sides of the second equation
Then add the first system and the second like this:
Because 0≠70, the system has no solutions
