Question

решите уравнение x:(17/66-1 7/14)= -2 1/7+7/17

Answer 1

x : (17/66 - 1 7/14)= -2 1/7+7/17
x : (17*7/462 - 1 7*33/462)= -2 17/119 + 7*7/119
x : (119/462 - 1 231/462)= -2 17/119 + 49/119
x : (- 1 112/462)= -1 136/119 + 49/119
x : (- 1 8/33)= -1 87/119
x : (- 41/33)= - 206/119
х=(- 206/119) * (-41/33)
х= 206*41 / 119*33
х= 8446/3927
х= 2 592/3927
