Question 161337
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*[invoke describe_linear_equation 1, 0, 3]

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.
