What is the value of x in the equation 1/3x-2/3=-18?

x = - 52

Step-by-step explanation:

The given equation is expressed as

x/3-2/3=-18

The first step would be to find the lowest common multiple of denominators of the left hand side and the right hand side of the equation. The lowest common multiple is 3

Then we would multiply the left hand side and the right hand side of the equation by the lowest common multiple. It becomes

x/3 × 3 - 2/3 × 3 = -18 × 33

x - 2 = - 54

Adding 2 to the left hand side and the right hand side of the equation, it becomes

x - 2 + 2 = - 54 + 2

x = - 52

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.

ome people is not even worth it to even try it in the air.
