2(x-y) = 8 (where 6 is equal to x)
Simplify:
2(6-y)=8
2(6 + -1y) = 8
(6 * 2 + -1y * 2) = 8
(12 + -2y) = 8
12 + -2y = 8
Solve for variable 'y':
Now you would move all terms containing y to the left, and all other terms to the right (they already are in this case).
Add '-12' to each side of the equation:
12 + -12 + -2y = 8 + -12
Combine like terms: 12 + -12 = 0
0 + -2y = 8 + -12
-2y = 8 + -12
Combine like terms: 8 + -12 = -4
-2y = -4
Divide each side by '-2'.
y = 2 (it's already simplified)
