Answer 1

1) -9

2) -6

3) 15

4) 3

5) -5

6) -16

7) 5

8) 8

Explanation:

`1) -6n+5=59\\=>-6n=59-5\\=>-6n=54\\=>n =(54)/(-6) =-9`

`2) -1+(x)/(6)= -2\\ => (x)/(6) =-2+1\\=>(x)/(6) =-1\\=> x=-6`

`3)(y)/(5) -3=0\\=>(y)/(5) =0+3\\=>(y)/(5)=3\\=>y=3*5 = 15`

`4)1-7b=-20\\=>-7b=-20-1\\=>-7b=-21\\=>b=(-21)/(-7) = 3`

`5)-k-5=0\\=>-k=0+5\\=>-k=5\\=>k(-1)=5\\=>(k(-1))/(-1) = (5)/(-1) \\=>k=-5`

`6)8a-1=-129\\=>8a=-129+1\\=>8a=-128\\=>a=(-128)/(8) =-16`

`7)-21=-1-4x\\=>-21+1=-4x\\=>-4x=-20\\=>x=(-20)/(-4) =5`

`8)12=8+(p)/(2) \\=>12-8=(p)/(2)\\=>(p)/(2)=4\\=>p=4*2=8`
