Помогите найти корни уравнений 4-x=5x + 22 5y+18=8y 16-2x=3x 42-2x=5x 3x+18=5x 5y-22=3y 3x+3x=5x+18 7y-5=3y+3 6x-45=2x-17 3-3y=7-13y 3x-2=7-x

1. х = - 3

2. у = 6

3. х = 3.2

4. х = 6

5. у = 9

6. х = 11

7. х = 18

8. у = 2

9. х = 7

10. у = - 0,4

11. х = 2,5

4-x=5x+22 - - > - x-5x=-4+22 - - > - 6x=18 - - > x = 18 / (-6) - - > x = - 3

5y+18=8y - - > 5y-8y = - 18 - - > - 3y=-18 - - > y = (-18) / (-3) - - > y = 6

16-2x=3x - - > - 3x-2x=-16-->-5x=-16--> x=16/5

42-2x=5x - - > x = 6

3x+18=5x - - > x = 9

5y-22=3y - - > y = 22/8=11/4

3x+3x=5x+18 - - > x=18

7y-5=3y+3 - - > y=2

6x-45=2x-17-->x=7

3-3y=7-13y - - > y=y=1

3x-2=7-x--> x = 9/4
