first you multiply b0th sides of the equation by 2, then add 7 to both sides to leave the x isolated.
[tex] \times 2 \\ + 7 \\ x \geqslant 25[/tex]
now you know that x is greater than or equal to 25, you start your line at number 25 and you continue it forever (or where the line on your paper stops). Good luck!
