Consider the equation
3(-x+2)-1=5x-4

9/8

Step-by-step explanation:

Step  1  :

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

Step  2  :

 9 - 8x  = 0  

Step  3  :

3.1      Solve  :    -8x+9 = 0  

Subtract  9  from both sides of the equation :  

                     -8x = -9  

Multiply both sides of the equation by (-1) :  8x = 9  

Divide both sides of the equation by 8:

                    x = 9/8 = 1.125  

One solution was found :

                  x = 9/8 = 1.125

inverse operation of addition

answer is a.
