Answer 1

14)x-9=-17

x=-17+9

x=-8

15)2x=-10

x=-10/2

x=-5

16)3x+2=4x-11

-x=-13

x=13

17)2x=6

x=6/2

x=3

18)x=-5

19)-2x+14=3x-1

-5x=-15

x=-15/-5

x=3

20)4x-5=-6x+11

10x=16

x=16/10

x=1,6

21)x/2=12/3

3x=24

x=24/3

x=8

22)5m-7-2m-2=0

3m=9

m=9/3

m=3

23)4t+9=3t-5

t=-14

24)y-8+5y=-3-y+7

7y=12

y=12/7

25)3. (x – 3) + 5 = x + 12

3x-9+5=x+12

2x=16

x=16/2

x=8

26) x + 4.(x - 1) = 9 - 2.(x + 3)

x+4x-4=9-2x-6

5x-4=-2x+3

7x=7

x=7/7

x=1

27) 2.(3x - 1) + 2 .(3 - x)= 0

6x-2+6-2x=0

4x=-4

x=-4/4

x=-1

28) -10 + 4 - 2x = -4x - 7

-6-2x=-4x-7

2x=-1

x=-1/2

29) 2.(x - 2)+ 5.(2 - x) + 6.(x + 1) = 0

2x-4+10-5x+6x+6=0

3x=-12

x=-12/3

x=-4

30) 3. (x - 2) - (1 - x) = 13

3x-6-1+x=13

4x=20

x=20/4

x=5

31) x - (x + 1) = 12 - (3x - 2)

x-x-1=12-3x+2

3x=15

x=15/3

x=5

32) x/3 - 1 + 3/4 = x/2 - 1/4

x/3-1/4=x/2-1/4

x/3=x/2

3x=2x

3x-2x=0

x=0
