Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
Answer:
Step-by-step explanation:

x = 8
Pythagorean theorem,
y² = 8² + 8²
= 64 + 64
y² = 128
y = √128
y = 11.31
