5x - (7+8+4x) = 56

4x + (15-3x) + 12=10

(21+x) - 34=11

19 + (13-7x+8x) = 59

4x - (12-25+3x) = 87

12-2x+3x-7=29 решите уравнение 5 кл

1. 5 х - (7+8+4 х) = 56

5 х-7-8-4 х = 56

х-15 = 56

х = 71

2. 4 х + (15-3 х) + 12=10

4 х+15-3 х+12=10

х+27=10

х=-17

3. (21+х) - 34=11

21+х-34=11

х-13=11

х=24

4. 19 + (13-7 х+8 х) = 59

19+13-7 х+8 х=59

32+х=59

х=27

5. 4 х - (12-25+3 х) = 87

4 х-12+25-3 х=87

х-13=87

х=74

6. 12-2 х+3 х-7=29

5+х=29

х=24
