Answer: I believe this will be your answer for this.

x = $2/729$ so basically this is your solution of x equaling to 2 over 729.

Select the graph of the solution. Click until the correct graph appears. 3x + 1 < 7 (line graph)

WARRIOR [948]

3x + 1 < 7...subtract 1 from both sides
3x < 7 - 1
3x < 6 ...divide both sides by 3
x < 6/3
x < 2

there will be an open circle on 2....because the problem has no equal sign...the line will be shaded to the left...because it is less then.
