Question

Упростите выражения: (-X-18 1/3)+(-19 2/7+y)= (b-73 6/7)+(-100+c)= (-61 2/9-k) +(t-68 1/6)=

Answer 1

(-X-18 1/3)+(-19 2/7+y)= -x - 18 1/3 - 19 2/7 + y = -x + y - 37 13/21

(b-73 6/7)+(-100+c)= b - 73 6/7 - 100 + c = b + c - 173 6/7

(-61 2/9-k) +(t-68 1/6)= -61 2/9 - k + t - 68 1/6 = -k + t - 129 7/18
