Question

question 12 all of the four

Answer 1

Answer:

12 a.  7x-1 =13

         7x= 14

          x=14/7

           x=2

   b.  2x+3(x-1) =5/2

        2x +3x - 3 =5/2

         5x = 5/2 +3

        5x = 11/2

        x= 11/10

   c.   (2x-3 ) /2 - (x+1)/3 =( 3x -8)/4

         (2x-3 )3 - (x+1)2 =( 3x -8)6/4

         6x - 9 - 2x -2 = (9x -24 )/2

         4x -11=(9x - 24)/2

         8x -22 = 9x -24

        24-22 = 9x-8x

        2= x

   d.  - 1.5x = - 4.5

          x= -4.5/-1.5

           x = 3

if the answer is useful pls mark as brainliest ......plsssssssss
