Debbie solved the linear equation 3(x + 4) - 2 = 16 as follows:
[Line 1] 3(x+4) - 2 =16
[Line 2]3(x+4)= 18
[Line 3]3x + 4 = 18
(Line 4]3x = 14
[Line 5] x = 4 2/3
She made an error between lines
A. 1 and 2
B. 2 and 3
C. 3 and 4
D. 4 and 5

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

i would say b) is your answer
