Answer:
just do the solution in the standard method.
Step-by-step explanation:
√x = 81 - y; -------- (1)
√y = 197 - x; ----------(2)
from the first equation, we can get,
x = (81 - y) ^2 = 6561 - 162y + y^2
from the second equation, we can get,
y = 197 - x = 197 - 6561 - 162y + y^2
= -6364 + 162y - y^2
y^2 - 161y + 6364 = 0
solving this quadratic equation, we can get
y = 91.28, then x = 107.67
y = 69.71, then x = 127.46
