The sum of two angles is 209. One angle is 28 degrees less than twice the other. Find the angles.
Let x = the 1st angle
y = the 2nd angle
Equation 1
x + y = 209
Equation 2
x = 2y - 28
Substitute x =2y-28 in equation 1
(2y-28) + y = 209
3y = 209+28
y = 79
x = 2(79)-28
x = 130
The angles are 79 and 130
