It looks like the problem is: Find y when x=6
2%2A%28x+-+y%29+=+8
2%2A%286+-+y%29+=+8
divide both sides by 2
6+-+y+=+4
subtract 6 from both sides
-y+=+4+-+6
Multiply both sides by -1
y+=+-4+%2B+6
y+=+2 answer
check answer:
2%2A%28x+-+y%29+=+8
2%2A%286+-+2%29+=+8
2%2A4+=+8
8+=+8
OK

2(x-y)=8 when x=6
.
All you need to do is to insert the given value of 'x' into the equation and solve for the unknown 'y':
.
The equation is:
2(x-y)=8
then they want you to solve for y when x=6
So, now we have:
2(6-y)=8
Start by distributing the 2 to each term inside the parenthesis:
12-2y=8
Now, subtract 12 from both sides:
-2y = -4
Finally, divide both sides by -2:
y = 2
