4x + 2y = 8
4(-2) + 2y = 8
-8 + 2y = 8
+ 8 + 8
2y = 16
2 2
y = 8
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
- 4 - 4
2y = 4
2 2
y = 2
4x + 2y = 8
4(3) + 2y = 8
12 + 2y = 8
- 12 - 12
2y = -4

Answer: 5/6
Step-by-step explanation:
Answer:
<h2>-8</h2>
Step-by-step explanation:
6y - 8 = c + 6y <em>subtract 6y from both sides</em>
6y - 6y - 8 = c + 6y - 6y
-8 = c
The equation has an infinite many solutions if when we get a true equation with no variable y.
Therefore c = -8
