y=5x+7

3y−15x=18


x−2y=6

3x−6y=18


y = 3x + 6
y=−13x−4
y=23x−1
y=23x−2

Answer 2

y=5x+73y−15x=18


How many solutions does it have

Answer 3

{−4x+y=6−5x−y=21

Answer 4

y=5x+7 One solution
3y−15x=18 One solution
x−2y=6 One solution
3x−6y=18 One solution
y = 3x + 6 One solution
y=−13x−4 One solution
y=23x−1 One solution
y=23x−2 One solution

Answer 5

Both equations represent lines that intersect at a single point, so they have one solution.
