Question:
Solution:
According to the data of the problem, we get the following linear system of equations:
x+145=180 EQUATION 1
2x+y=180 EQUATION 2
from EQUATION 1, we obtain:
x = 180-145 = 35
from EQUATION 2, we get:
y = 180-2x = 180-2(35) = 110
So that, we can conclude that the correct answer is:
x = 35
y = 110
