<u><em>⬇ Hey, the answer is down below! :) ⬇</em></u>
<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 = 
<u><em>In result we should have</em></u>
<u><em>as the answer!</em></u>
