Question

1----21x+1=11x+6

 

2----9x-23=13x-27

 

3----5(3-x)-7x=3(x-5)

 

4----7x-3(x-2)=3(x-5)

 

5----4(2x-1)-3(5x-2)+5=0

 

6----2(1-t)+1=3(+-3)-2+

 

7----3(4p-1)+9-4(p+1)=40

 

8----x - x=-3

           7

 

9----x + x = 21

       5    2

 

10---3x - 3= 3x

               2   2

 

me responde  ae por favor eu preciso muitao disso

Answer 1

1] 21x-11x =6-1

    10x = 5

    x=2

 

2) -23+27 = 13x-9x

   4=4x

   x=1

 

3) 15 - 5x -7x = 3x- 15

   15- 12x = 3x-15

  15+15= 3x+12x

30=15x

x=2

 

 

4) 7x - 3x- 6 = 3x-15

4x-6=3x-'15

4x-3x = -15+6

x= -
