Question

solve each of the following questions.Also represent the solutions  of questions from 1 to 3 graphically

please solve this sums plzźzzzzz​

Answer 1

Answer:

3=3(x+4)=21

3x+12=21

3x. =21-12

x. 9/3

x=. 3

6=. 3(x-3)=4(2x+1)

3x-9=8x+4

3x-8x=4+9

-5x= 13

x=.- 13/5

9=. 6x-9-2(1-x)=x+9

-54-2+2x= x+9

-56+2x=x+9

2x-x=9+56

x= 65

(3x+2)/2x-3=-3/2

by cross multiply

6x+4=-6x+9

6x+6x=9-4

12x=. 5

x=. 5/12
