Answer:
360
Step-by-step explanation:
The given digits are 1,2,3,4,5,6.
So, total number of digits = 6.
We need to find the number of different ways to form four-digit numbers using the digits, without repetition.
Total ways for first place = 6
After selecting 1 digit the number of remaining digits is 5. So,
Total ways for second place = 5
Similarly,
Total ways for third place = 4
Total ways for forth place = 3
Total number of ways =
Therefore, 360 four digit numbers are possible.

<u><em>For y:</em></u> x = -3
For y it stays the same.
<u><em>For x:</em></u> y = 2
For x it stays the same too.
<u><em>For 1.):</em></u>
Step-by-step explanation:
<u><em>For y there is no step-by-step explanation unfortunately.</em></u>
<u><em>For x there isn't a step-by-step explanation too unfortunately.</em></u>
<u><em>⬇ For 1.) there is a step-by-step explanation! ⬇</em></u>
For step 1 we should flip the equations.
6x + 8 = y
For step 2 we should add -8 to both sides.
6x + 8 + − 8 = y + −8
= 6x = y − 8
For step 3 we should divide both sides by 6.
= x =
