The answer they want: If you subtract the -2 x from the y side, then you get 4 y= 2 x + 8. Then you divide the entire equation by 4 getting y= 1/2 x + 8. Next, you can either put it in the calculator or you can put the numbers in the equation and solve it.

step-by-step explanation:

how many centimeters did the level of the salsa go down by?

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
