< = Angle

<R and <S are complementary angles, and <U and <V are also complementary angles. If m<R=y-2, m<S=2x+3, m<U=2x-y, and m<V=x-1, find the values of x, y, m<R, m<S, m<U, and m<V

y-2 + 2x+3 = 90
2x + y = 89

2x-y + x-1 = 90
3x - y = 91

add the two equations
5x = 180
x = 36

take it from there,
sub x=36 into one of the equations above to find y, then evaluate each of the angles
