Okay, so what they have given you is the values of X and y. So now we have to put the numbers into the given equation.
X is 20 and y is 18.
20+8-18
First, 20+8=28
28-18=10.
So the answer is 10.

Answer:
m = n = 2
Step-by-step explanation:
(m + n√2)(1 - √2)² = -2 + 2√2
(m + n√2)(1 - 2√2 + 2) = -2 + 2√2
(m + n√2)(3 - 2√2) = -2 + 2√2
3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2
(3n - 2m)√2 + 3m - 4n = 2√2 - 2
3n - 2m = 2
4n - 3m = 2
3n - 2m = 4n - 3m
n = m
4n - 3n = 2
n = 2
m = 2
Hope this helps.
