For Mijcar

Last 2 homework questions, one is basically a check. 10 I have done just want to make sure it's right. Question 11 I have not a clue and apparently there are 2 different solutions which they want.

10.a) 81^3(x+1)=9^2(x-1)

3^4(3(x+1))=3^2(2(x-1))

4(3(x+1))=2(2(x-1))

4(3x+3)=2(2x-2)

12x+12=4x-4

12x-4x=-12-4

8x=-16

x=-2

10.b) 81^3(x+1)=9^2(x-1)

9^2(3(x+1)=9^2(x-1)

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

2(3x+3)=2x-2

6x+6=2x-2

6x-2x=-6-2

4x=-8

x=-2
