Question

как решить (d-389)*3=807 8*(5400-s)=5536 t:(6400-6393)=8500 (119+h):8=75

Answer 1

(d-389)*3=807;
d-389=807/3
d-389=269
d=269+389
d=658.

8*(5400-s)=5536
5400-s=5536/8
5400-s=692
s=5400-692
s=4708

t:(6400-6393)=8500
t/7=8500
t=8500*7
t=59500

(119+h):8=75
119+h=75*8
119+h=600
h=600-119
h=481
