How many solutions does the system of equations have x-2y=6 and 3x-6y=18 one two infinitely many none

infinitely many

Step-by-step explanation:

I an going to solve these by elimination.  Multiply the first equation by 3

3(x-2y) = 3*6

3x - 6y = 18

This first equation multiplied by 3 is exactly the same as the second equation.  This means they are the same line.  If they are the same line, they have infinitely many solutions.

the y will be in still but your answer will be y x 3

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
