Question

(223440-130*x):35=6020

(31*550-x)*120=10200

Answer 1

223440-130х=6020×35
223440-130х=210700
130х=223440-210700
130х=12740
х=12740÷130
х=98

17050-х=10200÷120
17050-х=85
х=17050-85
х=16965

Answer 2

(223440-130*x):35=6020
223440-130*x=6020*35
223440-130*x=210700
130*x=223440-210700
130*x=12740
х=12740:130
х=98

(31*550-x)*120=10200
17050-x=10200*:120
17050-x=85
х=17050-85
х=16965
