Solve. Write the solution set in interval notation

Question

x+2≥6x-23

Answer 1

First, combine the x values on one side and the constants on the other side. If we subtract x from both sides we get 

2 >/= 5x - 23. Now add 23 to both sides and simplify. For interval notation, you will have an open interval to - infinity on one side and a number on the other. ( -∞, #].   The closed bracket is for the side of the interval that includes the number. The parenthesis is for either an interval that does not include the endpoint, or infinity.
