Question

Please help with 23, 25, and 27 ​

Answer 1

Answer:

I don't really know if its right I'm super sorry if it isn't

Step-by-step explanation:

23)  

8m + 3(2+8m) = 6-6m

8m + 6 + 24m = 6-6m

32m + 6 = 6-6m

- 6 from both sides

32m = -6m

38m = 0

∴ m = 0

25)

-7 +x = 8x - 7(-7x +1)

-7 + x = 8x + 49x - 7

-7 + x = 57x - 7

+ 7 on both sides

x = 57x

∴ x = 0

27)

2(3n + 9) - 12 = -4(5 + 5n)

6n + 18 - 12 = -20 - 20n

6n + 6 = -20 - 20n

+ 20n on both sides

26n + 6 = -20

- 6 on both sides

26n = -26

∴ n = -1
