please solve it u need help​

Answer 1

Step-by-step explanation:

4) 3n+15=37

3n=37-15

3n=22

n=22/3

b) 3p-1=23

3p=22

p=22/3

5)n-9=19

if n=10

10-9=1

not the solution of eq

b) 17n+5=25

if n=2

17*2+5

34+5=39

not the solution

6)let the angle be x

2 angles are equal

then 50+2x=180

2x=180-50

2x=130

x=130/2

x=65

8)let x be number

4+1/4x=20

b)15x-5=50

15x=45

x=3
