Найдите корень уравнения 1) x-4 1/2 = - 2 1/4

2) - x-6 4/5 = - 3 1/2

3) - X-11 1/2 = - 4 7/8

1) x-4 1/2 = - 2 1/4

x = - 2 1/4+4 1/2 = - 9/4+9/2 = (-9+19) / 4=9/4

x=9/4

2) - x-6 4/5=3 1/2

-x=3 1/2+6 4/5 = 7/2+34/5 = (35+68) / 10=103/10=10 3/10

-x=10 3/10

x = - 10 3/10

3) - x-11 1/2 = - 4 7/8

-x = - 4 7/8+11 1/2 = - 39/8+23/2 = (-39+92) / 8=53/8=6 5/8

-x=6 5/8

x = - 6 5/8
