Question

Solve for x: 5x + 7 - x - 2 = 6x + 3x - 16

Answer 1

Answer:

solution

5x -x +7 -2= 6x +3x -16

or,4x +5= 9x -16

or,5 +16= 9x -4x

or,21=5x

or,x=21/5

thus,x=4.2 #

Answer 2

Answer:

x =21/5 or 4.2

Step-by-step explanation:

Solve for x:

 5x + 7 - x - 2 = 6x + 3x - 16

Combine the like terms in LHS and in RHS.

      5x - x + 7 - 2 = 6x + 3x - 16

            4x + 5     = 9x - 16

Add 16 to both sides.

          4x + 5 + 16 = 9x

               4x  + 21  = 9x

Subtract 4x from both sides.

                       21 = 9x - 4x

                      21  = 5x

Divide both sides by 5.

                    21/5  = x

                         x = 21/5  or 4.2
