    when a question is asking for a 'solution' it is asking 'what are all the values of x that will cause this equation to be true?' Since the equation involves an inequality ('<' less than sign) there is more then one solution, in fact there are a great many. A number line is a visual representation of the solutions. When you see a question like this solve as you would an equality (an equation with an equal sign): \[4x-15<17\] \[4x <32\] \[x<8\] now in order to represent ALL the values less than eight you have to draw a number line and highlight them: |dw:1356370813323:dw| The open circle on eight means that eight is not actually included (it would be shaded in otherwise) and the arrow point to the left means that the solution continues to infinity
