Answer 1

Answer:

1) -9

2) -6

3) 15

4) 3

5) -5

6) -16

7) 5

8) 8

Step-by-step explanation:

$1) -6n+5=59\\=>-6n=59-5\\=>-6n=54\\=>n =\frac{54}{-6} =-9$

$2) -1+\frac{x}{6}= -2\\ => \frac{x}{6} =-2+1\\=>\frac{x}{6} =-1\\=> x=-6$

$3)\frac{y}{5} -3=0\\=>\frac{y}{5} =0+3\\=>\frac{y}{5}=3\\=>y=3*5 = 15$

$4)1-7b=-20\\=>-7b=-20-1\\=>-7b=-21\\=>b=\frac{-21}{-7} = 3$

$5)-k-5=0\\=>-k=0+5\\=>-k=5\\=>k(-1)=5\\=>\frac{k(-1)}{-1} = \frac{5}{-1} \\=>k=-5$

$6)8a-1=-129\\=>8a=-129+1\\=>8a=-128\\=>a=\frac{-128}{8} =-16$

$7)-21=-1-4x\\=>-21+1=-4x\\=>-4x=-20\\=>x=\frac{-20}{-4} =5$

$8)12=8+\frac{p}{2} \\=>12-8=\frac{p}{2}\\=>\frac{p}{2}=4\\=>p=4*2=8$
