1. 23+18+х = 41+х
2. (135+m)+65 = 135+m+65 = 200+m
3. (х+320)-186 = х+320-186 = х+134
4. у+12+54 = у+66
5. (15+75)+к = 90+к
6. (z+610)-186 = z+610-186 = z+424
7. (t+567)-169 = t+567-169 = t+398
8. 564-(45+h) = 564-45+h = 519+h
9. 71+f-43 = 28+f
10. 200-(58+p) = 200-58+p = 142+p
11. 56+х-39 = 17+х
12. 154-(b+24) = 154-b+24 = 178-b
13. х-21-43-64 = х-128
--------
128-(28+4) = 128-28-4 = 100-4 = 96
949-(5+49) = 949-49-5 = 900-5 = 895
215-93-7 = 215-(93+7) = 215-100 = 115
302-5-195 = 302-(195+5) = 302-200 = 102
81-38-2 = 81-(38+2) = 81-40 = 41
456-(356+99) = 456-356-99 = 100-99 = 1
--------
96-(39+56) = 96-95 = 1
734-(624+8) = 734-632 = 102
450-84-16 = 450-(84+16) = 450-100 = 350
212-75-25 = 212-(75+25) = 212-100 = 112
