You can put this solution on YOUR website!
7x + 4 > 4x + 13
subtract 4 from both sides
7x>4x+9
Subtract4x from both sides
3x>9
Divide both sides by 3
x>3
Solved by pluggable solver: DESCRIBE a linear EQUATION: slope, intercepts, etc
this equation defines a vertical line.

  • X intercept: 3. X intercept is the intersection of the line with the x axis.

  • Y intercept: not defined (the line IS vertical)

  • Slope: not defined, can be thought of as infinite

If you are going to graph this the straight line going through x=3
should be dashed and everything past x=3 is to be shaded.
