what is 8x-9z+3>8x-(15-8x)

Question

how to work problem

Answer 1

 8X -9Z + 3 > 8X - ( 15 - 8X)

 

      -9Z > -3 - 15 + 8X

 

 

      -9Z > -18 + 8X

  

        Z < -8/9 X + 2

 

 

        Graph Z = -8/9X + 2    on a 2 dimensional Z vertical .

 

       Z intercept : ( 0, 2 )   X intercept ( 9/4, 0)   Line dashed.

       

 

       Test ( 0,0 ) :     0 < 8/9(0) + 2

 

       Mark left part of the line from intercepts points hash mark as solution.
