Solve the inequality. Expression solution set using interval notation and graph the solution set using a number line. -15x+3<_-3(4x-7)

Thats supposed to be a greater than or equal to sign lol

solve just like an equation:

-15x+3 >= -3(4x-7)
-15x+3 >= -12x+21
-18 >= 3x
-6 >= x

"≥" can be obtained by using ">" key along with "option" key.
