3.5x-10>-3  add 10 to both sides
3.5x>7  divide both sides by 3.5
x>2
... now for the other inequality:
8x-9<39  add 9 to both sides
8x<48  divide both sides by 3
x<6
So we have x>2 and x<6, so the compound inequality is:
2<x<6  and this means that the solution set is:
x=(2, 6)
        
                    
             
        
        
        
So five plus three times x equals twenty because five is alone and you’re adding three times x and is represents the equal sign and twenty is alone. So the equation is this 5 + 3x = 20

The keyword is "sum" which tells you x, y, and z are being added. One half of the sum means that the sum of the three numbers is going to be divided by 2.
x + y + z
