Question

10-(2x+1)=4.(2x+3) calculo

Answer 1

10 - (2x + 1) = 4.(2x + 3)
10 - 2x - 1 = 8x + 12
9 - 2x = 8x + 12
9 - 12 = 8x + 2x
- 3 = 10x
10x = - 3
x = - 3/10  
   

x = - 3
      ------
         10

Answer 2

10 - (2x + 1) = 4.(2x + 3)

10 - 2x - 1 = 8x + 12

9 - 2x = 8x + 12

9 - 12 = 8x + 2x

- 3 = 10x

10x = - 3

x = - 3/10  

   

x = - 3

     ------

        10
