Step-by-step explanation:
2x = y-10
Rewrite as: 2x + 10 = y
Therefore:
2x+10 = y
2x +7 = 2y
Subtract the equations:
2x + 10 = y
- 2x + 7 = 2y
______________
3 = -y
Therefore y = -3
Substiture y = -3 into the second equation:
2x + 7 = 2(-3)
2x + 7 = -6
2x = -13
x= -6.5
Answer : (-6.5, -3)
The median is 1 because that is the number in the middle

Answer:
x= -13/30
Step-by-step explanation:
For this you have to get rid of the 3/5 first.
By doing this you do it on both sides.
Which will get you -3/5 on the left side.
X = 1/6
-3/5 on the right side
x = -13/30
