61-40: (2 х) + 17=73

37 + (80-6 х) : 8=41

98-8 * (1+63:х) = 18

помогите

61-40:2 х+17=73

40:2 х=61+17-73

40:2 х=5

2 х=40/5

2 х=8

х=8:2

х=4

37 + (80-6 х) : 8=41

(80-6 х) : 8=41-37

(80-6 х) : 8=4

80-6 х=8 х4

80-6 х=32

6 х=80-32

6 х=48

х=48:6

х=8

98-8 * (1+63:х) = 18

8 + (8*63:х) = 98-18

8+504:х=80

504:х=80-8

504:х=72

х=504:72

х=7
