Answer 1

Step-by-step explanation:

1)n-3=8

=> 3+8=11

=> 11-3=8

★ n=11

2)n+6=19

=>19-6=13

★n=13

3)8n=2000

$= > \frac{2000}{8}$

=>250

★n=250

4)2n-6=36

=>36+6

=>42

$= > \frac{42}{2}$

=>21

★n=21

5)3n+6=36

=>36-6=30

$= > \frac{30}{3}$

=>10

★n=10

6)n-5=9

=>9+5=14

★n=14

7)2n-8=16

16+8=24

$= > \frac{24}{2}$

12

★n=12

8)x-2.6=7.5

=>7.5+2.6

=10.1

★x=10.1

9)3n=150

$= > \frac{150}{3}$

=>50

★n=50

10)12p=144

$= > \frac{144}{12}$

=>12

★p=12

11)2/5p=40

=>2p/5=40

=>2p=40×5

=>2p=200

★p=200/2=100

12)4(n-6)=20

=>20+6=26

$= > \frac{26}{4}$

=>6.5

★n=6.5
