Answer:
1) -9
2) -6
3) 15
4) 3
5) -5
6) -16
7) 5
8) 8
Step-by-step explanation:
[tex]1) -6n+5=59\\=>-6n=59-5\\=>-6n=54\\=>n =\frac{54}{-6} =-9[/tex]
[tex]2) -1+\frac{x}{6}= -2\\ => \frac{x}{6} =-2+1\\=>\frac{x}{6} =-1\\=> x=-6[/tex]
[tex]3)\frac{y}{5} -3=0\\=>\frac{y}{5} =0+3\\=>\frac{y}{5}=3\\=>y=3*5 = 15[/tex]
[tex]4)1-7b=-20\\=>-7b=-20-1\\=>-7b=-21\\=>b=\frac{-21}{-7} = 3[/tex]
[tex]5)-k-5=0\\=>-k=0+5\\=>-k=5\\=>k(-1)=5\\=>\frac{k(-1)}{-1} = \frac{5}{-1} \\=>k=-5[/tex]
[tex]6)8a-1=-129\\=>8a=-129+1\\=>8a=-128\\=>a=\frac{-128}{8} =-16[/tex]
[tex]7)-21=-1-4x\\=>-21+1=-4x\\=>-4x=-20\\=>x=\frac{-20}{-4} =5[/tex]
[tex]8)12=8+\frac{p}{2} \\=>12-8=\frac{p}{2}\\=>\frac{p}{2}=4\\=>p=4*2=8[/tex]
