Question

How many solutions does this system of equations have? y=3x+1 y=3x+7

Answer 1

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 2

Answer:

Step-by-step explanation:

this system has no solutions

y=3x+1

y=3x+7 we will multiply -1 second equation

y=-3x-7

0=6
