The solution is: x= 7 and y = 2
Step-by-step explanation:
Given equations are:

Putting x = 3y+1 in equation 2 from equation 1

Subtracting 1 from both sides

Dividing both sides by 7

Putting y=2 in equation 1

Hence,
The solution is: x= 7 and y = 2

Answer: y=4x-2
Step-by-step explanation:
Since you are looking for y-intercept, the point has to be on the vertical line and the slope is 4 so it has to go up 4 to the right 1
The answer is 54 because you add them
