Please I need help with this homework

Step-by-step explanation:

5. 6x-8=9x+4

6x - 9x = 4+8

-3x = 12

x = -4

check, 6(-4) - 8=9(-4) + 4

-24-8 = -36+4

-32 = -32

6. 5a - 10 = 9a - 6

5a-9a = -6+10

-4a = 4

a = -1

check, 5(-1) -10 = 9(-1) -6

-5-10 = -9-6

-15 = -15

7. 8m-24 = 9-3m

8m + 3m = 9+24

11m = 33

m = 3

check, 8(3)-24 = 9- 3(3)

24-24 = 9-9

0 = 0

8. 10- 3z = z + 30

10-30 = z +3z

-20=4z

-5 = z

check, 10 - 3(-5) = (-5)+30

10+15 = 25

25=25

9. 3k - 14 = 10 +5k

3k - 5k = 10+14

-2k = 24

k = -12

check, 3(-12)-14 = 10+5(-12)

-36-14 = 10-60

-50 = -50

10. 6c + 8 = 2c -16

6c - 2c = -16-8

4c = -24

c = -6

check, 6(-6)+8 = 2(-6) - 16

-36 + 8 = -12 - 16

-28 = -28
